Oh, no, not redox again....

OILRIG – oxidation is loss, reduction is gain

Elements – oxidation state is always 0

Compounds always 0, BUT

Compound ions and any other ions add up to their formal charge.

Remember rules:

F-1 (always)

O-2 (except with F)

Halogens-1 (except with F or O)

Group1 +1

H+1 (but -1 in metal hydrides)

Group2  +2

Remember this is a hierarchy, top rules rule and if you need to know ones that aren’t here, it’s based on electronegativity.
