An atom has 7 protons, 8 electrons, and 7 neutrons. What is the charge of the atom and what type of ion is it?

An atom containing 7 protons, 8 neutrons, and 7 electrons is charge-neutral.

Explanation:

An atom is composed of protons (positively charged), neutrons (no charge) and electrons (negatively charged). The excess or defect of electrons in relation to protons determines the charge of an atom.

Negative Charge and it is an Anion
