    If an atom or a molecule of hydrogen is suspended in a vacuum jar where would it go, up or down?

    whether it will move down due to gravity or move up because its most light gas and further there is no other molecules of air because it is in vacuum. this may not be practically done but what theory says.

    It wouldn't move up or down, a single molecule would have a randomized path. An object filled with hydrogen, a balloon for example, would fall.

      i still have a question that; why does the atom wouldn't fall down due to gravity? isn't gravity able to effect such small thing or atom has something greater than gravity?

      If it was cooled to absolute zero, probably, but otherwise it has too much energy. It's the same reason that our atmosphere doesn't collapse or float away. There is enough energy in the gases to balance with gravity.

    When looking at a single molecule of hydrogen, that molecule has a lot of kinetic energy, it moves and ricochets off the walls of the container, and has enough energy to "defy" gravity. This would happen with most gasses, and most other molecules if there were just by themselves since they too would behave like a gas.

    If you had a balloon of hydrogen in a vacuum chamber, however, that would be different. Hydrogen-filled objects float in air because hydrogen is light enough to prevent the walls of the balloon from collapsing from air pressure, while also having a lower density than air. The result is an object that floats. But it was in a vacuum chamber, the object would sink from gravity, as it would overall not have enough energy to counteract gravity, and nothing, for all intents and purposes, is less dense than a vacuum (or an evacuated chamber).
