Question

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?

Answer 1

0

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.
