9.1/S3.1.6 How do I Assign Oxidation States? [SL IB Chemistry]

1) OS of elements are zero
2) Sum of OS = charge on the molecule/ion
3) OS of H in a compound is +1 (except when with a metal OS=-1)
4) OS of O in a compound is -2 (except in H2O2 where OS = -1)
5) Fluorine in a compound is -1
6) OS of metal in a compound = +(valence electrons)
7) Halogen = meh probably -1.

These videos will be the reason I will be able to get a good grade in HL chemistry, thank you.

hi for the last one c3h8 why did u list down for the hydrogen.. u said we should not list down for hydrogen

At 3:15 +4 and +1, +1, +1, +1 is not equal to zero

Nascent oxygen or any other atom of a polyatomic molecule also has an oxidation state of 0, right?
