What is the charge of a neutral atom?

Explanation:
Neutral atoms have no net charge because the positive charges from protons balance the negative charges from electrons. In a neutral atom, the number of protons equals the number of electrons, so the total positive charge cancels the total negative charge, giving zero net charge. The nucleus contributes positive charge and the surrounding electrons contribute negative charge, but their magnitudes match in a neutral atom. If electrons are gained or lost, the balance shifts and the atom becomes positively or negatively charged; pressure or other conditions don’t determine the net charge. So, the charge of a neutral atom is no net charge.
