When it has gained one electron, forming Hydride ions
Hydrogen have an oxidation number of -1 in metal hydrides
negative numbers --go to the discussion spot and it will help you. :)
0, 1 and 2 oxidation states
The oxidation state of iron in two moles or atoms of elemental iron is zero. If you mean iron (II), the oxidation state is +2.
The oxidation state (or number) is zero. This is true for any element in any of its allotropic elemental forms.
The most common oxidation state for chlorine is 1- (negative one).

yes
A pure metal has the oxidation state zero.
Boron
The oxidation state of N in HNO3 is +5. Oxygen is -2 and H is +!.
