H2
Hydrogen exists as a diatomic gas.

We always use the 'H2' molecule when referring to hydrogen because the atoms run around as couples.
I believe that reference to a single atom of 'H' only actually applies to the hydrogen ion ('H+') which can exist in the free state.

Hydrogen gas has two molecules of hydrogen bonded together. That means you need the "two" in its name. If you are writing it you use the two as a subscript. If you are saying it you could say "H2" or you could say "hydrogen" (if it is obvious you are talking about the gas)

You've gotta say H2 because Hydrogen is part of the "HOBrFNCl" group- Hydrogen, Oxygen, Bromine, Fluorine, Nitrogen, and Chlorine can only exist if there is 2 of them.

H2
hydrogen gas are diatomic, (they go round in pairs)

When you are talking about it you can say hydrogen. But it is more stable as H2.

hydrogen is just a rule for the nomenclature, and there are many like that.
It is H2 in fact because, the H atoms satisfy the octect rule and are more happy like that! :), like Cl2, Br2....

Is H2, i dunno the cause, i think its more stable on that way
