What happens to an atom when it gets oxidized?

A. It's oxidation state increases

B. It's atomic number increases

C. its oxidation state decreases

D. It's ionic charge decreases

A. It's oxidation state increases

Explanation:

A chemical reaction that involves the moving of electrons is known as oxidation. In oxidation, an atom, molecule, or ion loses one or more electrons in a chemical reaction.

When oxidation occurs, an element loses electrons and its oxidation number increases (becomes more positive), this means the oxidation state of the chemical species increases.
