Question

Quizplus · Accepted Answer

In an electrically neutral atom, the positive charges of the protons in the nucleus are balanced by the negative charges of the electrons that surround the nucleus. Therefore, the number of protons in the nucleus is equal to the number of electrons in the neutral atom. The number of neutrons in the nucleus can vary without affecting the atom's electrical charge.
