#### Answer:

3 electrons are gained.

#### Explanation:

Oxidation states with **"n+"** mean there are *n* number of electrons **lost** or **removed** from the total number of electrons of the ground state element . **"n-"** on the other hand means there are *n* number of electrons **gained** or **added** to the total number of electrons of the ground state element.
