Answer:

One electron per single hydrogen atom.

Explanation:

Hello!

In this case, given the reaction:

$H_2+O_2\rightarrow H_2O$

Whereas we can identify the following half-reaction for hydrogen:

$H_2^0\rightarrow H_2^+$

Whereas we see that each single hydrogen atom gains one electron in order to go from 0 to +1, which is also related to an oxidation half-reaction.

Best regards!
