Oxidation numbers

Postby vpena_1I » Thu Feb 20, 2020 5:09 pm

I read somewhere online that one of the rules for finding the oxidation number of an element is that H is always +1.
If that's the case, how is H2 neutral? Or is the "rule" just an oversimplification?

H2 has a neutral charge because it is the most stable form of hydrogen. Other then that, the oxidation number of hydrogen is +1.

I think H is +1 in oxidation state senses also because it generally will act as the positive cation in ionic elements/have lower electron affinity in a covalent interaction. H2 is diatomic and as mentioned, is very stable and the electrons are equally shared.

H2 is an exception because it is a diatomic and in its most stable form.

Keep in mind that any molecule made of only one element will have oxidation number of 0 if it's neutral charge.

Are all diatomic molecules neutral charge?

Diatomic molecules of the same atom (homonuclear) should all be neutral charge.
