Answer:
0
Explanation:
Protons have a positive + charge.
Neutrons have a neutral (0) charge.
Electrons have a negative - charge.
In order to determine the charge of an atom, we only look for the protons and neutrons.
We are given 2 protons and 2 electrons
+2 charge + -2 charge = 0 charge.
This atom is a neutral atom.
