What is oxidation in terms of oxygen?

Oxidation is the gain of oxygen.

What is reduction in terms of electrons?

Reduction is the gain of electrons.

How is the oxidation state of an element defined?

The oxidation state is a number assigned to an atom in a compound indicating its degree of oxidation.

What is a redox reaction?

A redox reaction is a chemical reaction where oxidation and reduction occur simultaneously.

What role does an oxidizing agent play in a reaction?
