Each electron in an atom has a charge of - 1 and each proton has a charge of + 1. What is the overall charge of an atom that contains 2 electrons and 2 protons?

0

Step-by-step explanation:

We are given that each electron in an atom has a charge of - 1 and each proton has a charge of + 1.

The charge of 2 electrons will be:

2 * (-1) = - 2

The charge of 2 protons will be:

2 * 1 = 2

The overall charge is the sum of the charge of the 2 electrons and the 2 protons. That is:

-2 + 2 = 0

The overall charge is 0.
