For elements to maintain a neutral charge, which two particles must have equal numbers? (2 points) electrons and protons ions and electrons neutrons and ions protons and neutrons

Option (a) is the correct answer.

Explanation:

In order to maintain a neutral charge the number of protons must be equal to the number of electrons.

For example, in a neutral carbon atom the atomic number or number of protons is 6. Also, number of electrons present in carbon atom will be 6.

Thus, we can conclude that out of the given options for elements to maintain a neutral charge number of electrons and protons must be equal.
