Answer 1

Answer:

+1

Fluorine always has oxidation state of –1. Elements of Group 1 (IA) (except hydrogen) have an oxidation state of +1 in compounds. Elements of Group 2 (IIA) have an oxidation state of +2 in compounds.

Answer 2

Here's your answer mate

Oxidation number of Group 1 (IA) group elements in all their compounds is +1 except hydrogen .

in Hydrogen :

• when it is combined with Non-metal it's oxidation number is +1 .
• And when it is combined with metals it's oxidation number is -1.
