What is the ion electron equation showing the formation of hydrogen gas?

Answer 1

A chemical equation, like all equations, contains an equals sign ( = ). It shows a chemical reaction, where something turns into something else. You probably mean the chemical symbol that would represent hydrogen. The symbol for an atom of hydrogen is H. In hydrogen gas the atoms usually pair up into hydrogen molecules for which the symbol is H2. If the gas is very hot the molecules dis-associate, so then the symbol will be just H, or sometimes (H) to make it clear that monatomic hydrogen is referred to. If you want an equation : H2 + heat = 2 (H)

Answer 2

Hydrogen gas is produced by two Hydrogen atoms bonding to gain an octet, due to how it is diatomic. The formula for hydrogen gas is H2. The other diatomic elements are carbon, nitrogen, oxygen, fluorine, chlorine, bromine, and iodine.

Answer 3

there is none, it is a noble gas and therefore does not form an ion

Answer 4

2H+(aq) + 2e- = H2(g)

Answer 5

2H+ + 2e- --------> H2

Answer 6

it is H2.
