Explanation:

An ion has a net charge of 3+

ion has 8 protons

How many electrons does it have

A neutral atom has equal number of electrons and protons.

If a neutral atom loses electron it acquires a positive charge.

So to acquire 3+ charge the atom must have lost three electrons.

So the number of protons exceeds the number of electrons by 3.
