Select the correct answer.

An ion has a net charge of 3+. If this ion has 8 protons, how many electrons does it have?

A. 3

B.

un

OC. 7

D.

00

E.

11

5

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.
