Answer 1

When the positive charge on an atom or an ion increases or the negative charge on them decreases it is called oxidation.

Explanation:

Oxidation is the process in which an atom or ion loses electrons, so its positive charge increases (or its negative charge decreases); the reverse gain of electrons is reduction.
