Final answer:
If an atom is neutral, it means the number of protons is equal to the number of electrons.
Step-by-step explanation:
If an atom has no charge or a neutral charge, it means that the number of protons (+) is equal to the number of electrons (-) in the atom. This is because protons are positively charged particles found in the nucleus of an atom, while electrons are negatively charged particles that orbit around the nucleus. The positive charge of the protons cancels out the negative charge of the electrons, resulting in a neutral atom.
