Chemical Nomenclature and Chemical Formulas

Updated on January 28, 2015

Introduction

Chemistry is involved with various and diverse interactions of matter either around us or simply inside the laboratory. These are described using the language of chemistry which consists of symbols, formulas and equations.

Symbols are used as shorthand abbreviations for elements composed of a single capital letter or a capital letter and one or two small letters like H, O, Cl, Na, or Unq.

Formulas are combinations of symbols such as CO2 for carbon dioxide, C6H22O11for table sugar and HCl for hydrochloric acid.

Chemical reactions are composed of elements and compounds which are described through chemical equations using symbols and formulas.

Chemical Symbols

Chemical symbols are shorthand abbreviations for elements composed of a single capital letter or a capital letter and one or two small letters.

Chemical Formula

Chemical formula indicates the relative number of atoms of each element in a substance. It consists of symbols of elements and subscripts which give the number of atoms of each element.

Examples:

  • The formula of water is H2O

There are 2 atoms of Hydrogen and 1 atom of oxygen

  • The formula of glucose is C6H12O6

There are 6 atoms of Carbon, 12 atoms of Hydrogen and 6 atoms of Oxygen.

In writing formulas, the total positive charges plus the total negative charges must equal to zero since the compound is electrically neutral.

Examples of common, simple and polyatomic ions

Rules in writing formulas of compounds

There are basic rules in writing formulas of compounds. These are:

  1. Write first the symbol of the positive ion followed by the symbol of the negative ion or radical. A radical or polyatomic ion is a group of atoms which acts as a single atom.
  2. Criss-cross: the valence of the positive ion becomes the subscript of the negative ion, while the valence of the negative ion becomes the subscript of the positive ion. (You have to disregard the sign) Example: Al+3 O-2 = Al2O3
  3. If the valence is numerically equal, there is no need to criss -cross since the sum of the valence is zero. Example: Ca+2O-2 = CaO
  4. Do not write the subscript if it is only 1.
  5. If the subscript of the radical is greater than 1, the radical is enclosed with a parenthesis. Example: Mg-2PO-3 = Mg3 (PO2)2
  6. Subscripts should be reduced to the lowest ratio. Example: Sn+4 O-2 = Sn2 O4 = SnO2

How Are Compounds Named

There are several types of compounds. These are the acids, bases, salts, and oxides. This lesson will show you how to name each compound correctly.

Acids

These are compounds of weakly bonded H atoms. In solution, they release ions. A given nonmetal may form a series of acids.

Naming Acid Compounds
Naming Acid Compounds
Common Acids with their Formulas and Uses
Common Acids with their Formulas and Uses

Common Acids

HBrO3 - Bromic acid

HlO3 - Iodic acid

HClO3 - Chloric acid

HBO3 - Boric acid

HMnO3 - Manganic acid

H2SO4 - Sulfuric acid

H3PO4 - Phosphoric acid

H3AsO4 - Arsenic acid

  • Note that all acids above have names ending in ‘ic’ attached to the stem of the name of the nonmetal. The number of oxygen atoms in common acid is either 3 (column 1) or 4 (column 2). You have to remember this:

To name a series of acids formed by a given nonmetal, consider the following:

HClO4 perchloric acid

HCIO3 chloric acid

HCLO2 chlorous acid

HCIO hypochlorous acid

HCI hypochloric acid

The system adopted is as follows:

  1. The suffix ‘ic’ denotes the common acid (HCIO).
  2. The suffix ‘ous’ denotes an acid containing one less oxygen atom than the common acid (HCIO2).
  3. The prefix ‘hypo’ with the suffix ‘ous’ denotes an acid with two less oxygen atoms than the common acid (HCIO).
  4. The prefix ‘per’ with the suffix ‘ic’ denotes an acid containing one more oxygen atom than the common acid (HClO4).
  5. The prefix ‘hydro’ with the suffix ‘ic’ denotes an acid with no oxygen (HCl).

Answer the following:

1. Name the following acids:

a. HbrO2

b. HI

c. H2SO3

d. HMnO4

e. H2S

2. Write the chemical formula of the following:

a. Hydrobromic acid d. Hypoiodous acid

b. Nitrous acid e. Bromous acid

c. Periodic acid

  • Note: (c) is read as per-iod-ic acid.

Bases

These are the compounds identified by the presence of the hydroxide group (OH). Name of the metallic portion first followed by the word hydroxide.

Examples:

NaOH - Sodium Hydroxide

Fe(OH)2 - Iron(II) Hydroxide or Ferrous Hydroxide

Fe(OH)3 - Iron(III) Hydroxide or Ferric Hydroxide

The strengths and weaknesses of acids and bases

Salts

Salts are formed when metallic atoms replace the weakly bonded hydrogen atoms of an acid. They are named after the acid from which they are formed. The name of the metal comes first, followed by the name of the nonmetallic group. The ending ‘ic’ is changed to ‘ate’ and the ending ‘ous’ to ‘ite’. For salts with no oxygen atom, the prefix ‘hydro’ is dropped and ending ‘ic’ is changed to ‘ide’.

For example, the acid HNO3 (nitric acid) forms the salt KNO3 (potassium nitrate), when the metallic atom K places H atom of the acid. As another example, the acid HNO2 (nitrous acid) forms the salt KNO potassium nitrate). The ending ‘ous’ of the acid is changed to ‘ite’.

HI (hydroiodic acid) forms the salt KI (potassium iodide). Since there is no more hydrogen atom in the salt, the prefix “hydro” of the acid name is dropped. The ending ‘ic’ of the acid is changed to “ide’ in salt.

♦ Consider the following series:

NaClO4 - Sodium Perchlorate

NaClO3 -Sodium Chlorate

NaClO2 - Sodium Chloride

NaClO - Sodium Hypochloride

NaCl - Sodium Chloride

These salts are formed by replacement of the H of the series of acids.

♦ Give the name of each of the following salts:

a. K2SO4 d. Lil

b. Ca3(PO4)2 e. KmnO4

c. Na2CO3

♦ Write the chemical formula of:

a. Sodium Nitrate

b. Magnesium Chloride

c. Calcium Sulfite

d. Sodium Hypobromite

e. Ammonium Periodate

When a metal has a variable oxidation number, its name is followed by the oxidation number written in Roman numeral enclosed in parenthesis. The old method used the stem of the Latin name and the suffixes ‘ous’ and ‘ic’ for the lower and higher states, respectively.

Examples:

FeCI2 – iron (II) chloride or ferrous chloride

FeCI3 – iron (III) chloride or ferric chloride

Other Metallic Ions with Variable Oxidation Number

Sn
+2
tin(II) or stannous
Sn
+4
tin(IV) or stannic
Hg
+1
mercury(I) or mercurous
Hg
+2
mercuric(II) or mercuric
Cu
+1
copper(I) or cuprous
Cu
+2
copper(II) or cupric
Au

gold(I) or aurous
Au
+3
gold(III) or auric
Pb
+2
lead(II) or plumbous
Pb
+4
lead(IV) or plumbic

Acids, Bases and Salts

Oxides

Oxides are compounds of oxygen with metals or nonmetals. Name the metal or the nonmetal first. Then use the prefixes di, tri, tetra or penta before the term oxide to indicate the number of oxygen atoms present. In case where the number of oxygen atom present can determine from oxidation number of the combined metal, the prefix is omitted.

Examples:

NO2: Nitrogen Dioxide

N2O4: Dinitrogen Tetroxide

P2O5: Phosphorus Pentoxide

PbO: Lead(II) oxide or Plumbous Oxide

PbO2: Lead(IV) oxide or Plumbous Oxide

Questions for Study and Review

I. Name the following compounds by identifying the oxidation number of the metal as you name the compounds listed below:

  1. CoBr2
  2. PbS
  3. CrSO4
  4. Fe(NO3)2
  5. Sn(ClO4)3

II. Formula Writing: Write the correct chemical formula of the following:

  1. Calcium carbonate
  2. Magnesium hydroxide
  3. Copper sulfate
  4. Carbon tetrachloride
  5. Potassium bromate
  6. Ammonium hydroxide

      The primary function of chemical nomenclature is to ensure that a spoken or written chemical name leaves no ambiguity concerning which a chemical compound the name refers to, each chemical name should refers to a single substance. The names also conveys some information about the structure or chemistry of a compound. Also important aim is to ensure that each substance has a single name, although a limited number of alternative name is acceptable in some cases.

      Chemical nomenclature - The process of giving unambiguous chemical formulas or chemical names to elements and compound. Today the rules for writing chemical formulas and naming chemicals are set by the Nomenclature Committee of the International Union of Pure and Applied Chemistry (IUPAC). Chemical names and formulas that follow the rules of this committee are said to follow IUPAC no menclature.

      Chemical nomenclature and Chemical formulas are very useful in terms of chemistry and it can also relate to our daily life which we can used it as a basis to understand how atoms or chemicals form, to know the abbreviation of their names and how it will react if we apply the formulas. So that, acid bases and salt are commonly used in preparing nor cooking food and it is important for us to know what are the content of acid, base and salt etc. to be more knowledgeable.

      The relevance of chemical nomenclature in hospitality management are

      There are over 19 million known chemical substances. Without some type of system, naming these substances would be hopelessly complicated. The system used in naming substances is called chemical nomenclature.There are two major divisions to the International Union of Pure and Applied Chemistry IUPAC system:

      inorganic nomenclature

      organic nomenclature

      Organic compounds contain carbon, usually in combination with hydrogen, oxygen, nitrogen, and/or sulfur.All other substances are inorganic compounds, divided into three basic categories:

      ionic compounds

      molecular compounds

      acids

      Chemical Nomenclature, in simple terms, is the proper naming of elements and compounds (acids, salts, bases, and oxides) that makes up chemical equations in chemical reactions. Without symbols for elements, it is then impossible to make chemical formulas for compounds. This naming system is very important for without it we won't know which is which and what is what. In experiments, if the components needed have no labels or names, how could we possibly identify what are we going to add or mix in a chemical solution. This may give rise to confusion and confusion will result to failure and possible lab accidents. That's why knowing each of these names for elements and compounds is significant.

      In the field of communication, identification and classification of information is really of great significance. If we don't identify which information came from which or whoever, then it's like palgiarism or lying. We also have remember names of different personalities.

      Nomenclature is the systematic approach to naming chemical compounds. This is only concerned with naming very simple compounds. There are several types of compounds. These are the acids, bases, salts, and oxides. On the other hand, chemical formula is the representation of the composition of compounds. It contains the symbol and formula of elements or radicals and the number of atoms of each element. In writing formulas, we should know the correct symbols of element and radicals. Valence denotes the number of electrons in the outermost energy level while radicals are group of elements which act as one or a single atom. Also, there are rules to be followed in writing formulas. As a future educator, it is important to understand the lesson well and be able to write formulas, balance chemical equations and even calculate the percentage composition of a compound for our future students to learn.

      Chemical nomenclature is concerned with naming chemical compounds and writing their formulas. A chemical nomenclature is a set of rules to generate systematic names for chemical compounds. A chemical formula is an expression which states the number and type of atoms present in a molecule of a substance. The type of atom is given using element symbols. The number of atoms is indicated by a subscript following the element symbol. Naming compounds using a fixed set of rules is important so that all compounds are recognized globally by the same name to avoid confusion and misunderstanding. Compounds are named so as to distinguish one compound from another. At times the chemical name of a compound is very long and so to communicate better, a common word/name is used instead. Compounds have a common name, a proper name and chemical formulae. A chemical formula clearly shows the composition of a substance. It not only reveals the identity of the constituent elements, but also their fixed ratio by mass. The chemical formula also stands for one molecule of a substance.

      In a chemical equation, the formula represents one mole of a reactant or product. Having connection in teaching, teachers might have diverse students. Different cultures, personalities, and names. Every teacher must know the name of his students and be able them to differentiate. Each name has its own origin and it should be accepted and respected.

      chemical nomenclature is a set of rules to generate systematic names for chemical compounds. When forming compounds, it is important to know something about the way atoms will react with each other. One of the most important manners in which atoms and/or molecules react with each other is the oxidation/reduction reaction. Oxidation/Reduction reactions are the processes of losing and gaining electrons respectively; oxidation numbers are assigned to atoms and compounds as a way to tell scientists where the electrons are in a reaction. It is often referred to as the "charge" on the atom or compound. The oxidation number is assigned according to a standard set of rules, knowing the oxidation number of a compound is very important when discussing ionic compounds. Ionic compounds are combinations of positive and negative ions. They are generally formed when nonmetals and metals bond, as a future educator we must remember the names of our student and not give them a name that can embarrass or can humiliate them.

However, it is important to be able to recognize and name all chemicals in a standardized way. Molecular compounds are made when two or more elements share electrons in a covalent bond to connect the elements. Typically, non-metals tend to share electrons, make covalent bonds, and thus, form molecular compounds. Having relation to my course it is important to know our students each or one by one as what and who they are.

      Chemical nomenclature is the term given to the naming of compounds. Chemists use specific rules and "conventions" to name different compounds. This section is designed to help you review some of those rules and conventions. The primary function of chemical nomenclature is to ensure that a spoken or written chemical name leaves no ambiguity concerning which chemical compound the name refers to: each chemical name should refer to a single substance. A less important aim is to ensure that each substance has a single name (although a limited number of alternative names is acceptable in some cases). The form of nomenclature used depends on the audience to which it is addressed. As such, no single correct form exists, but rather there are different forms that are more or less appropriate in different circumstances. A common name will often suffice to identify a chemical compound in a particular set of circumstances. However, in a few specific circumstances (such as the construction of large indices), it becomes necessary to ensure that each compound has a unique name.

      In discussing chemistry nomenclatures is it necessary to identify the type of compound including stoichiometry and type of constituent atoms. The first separation of importance is to distinguish between inorganic and organic compounds. Unfortunately, this separation is not always clear. even to experienced chemists. Historically (two centuries ago) the definitions were that inorganic compounds were synthesized by geological systems and organic compounds were found in biological systems. The modern definitions argues that organic compounds are any molecule containing carbon and by default this means that inorganic chemistry deals with molecules lacking carbon. The confusion arise when chemists that study carbon based materials like diamond or graphite, but that argument is beyond the scope of this text. The following sections presents the current nomenclature rules for inorganic and organic molecules.

      It is necessary to know the names of the chemicals for it gives us the idea of their uses. Naming chemicals is as important as knowing my future students by name. So, I will be able to record correctly their grades according to their performance.

      A chemical nomenclature is a set of rules to generate systematic names for chemical compounds. Chemists use specific rules and "conventions" to name different compounds. When forming compounds, it is important to know something about the way atoms will react with each other. One of the most important manners in which atoms and/or molecules react with each other is the oxidation/reduction reaction. Oxidation/Reduction reactions are the processes of losing and gaining electrons respectively.

      As a mass communication student, we should know how to follow the rules in making article because we offer information and build a relationship with your newsletter subscribers and to give your clients a deeper understanding on a topic.

      Nomenclature is the systematic approach to naming chemical compounds. This is only concerned with naming very simple compounds. There are several types of compounds. These are the acids, bases, salts, and oxides. On the other hand, chemical formula is the representation of the composition of compounds. It contains the symbol and formula of elements or radicals and the number of atoms of each element. In writing formulas, we should know the correct symbols of element and radicals. Valence denotes the number of electrons in the outermost energy level while radicals are group of elements which act as one or a single atom. Also, there are rules to be followed in writing formulas. As a future educator, it is important to understand the lesson well and be able to write formulas, balance chemical equations and even calculate the percentage composition of a compound for our future students to learn.
