Answer 8

Gain or loss of electrons

Question 9

What is the oxidation state?

Answer 9

The charge that would exist on an individual atom if the bonding were completely ionic

Question 10

What is an oxidising agent?

Answer 10

A species which oxidises something else therefore it must be itself reduced
