Which two types of particles are present in equal numbers in an atom, but not in an ion?
group of answer choices

The protons and electrons are present in equal numbers in a neutrally charged atom.This means that the atom has an overall charge of 0.

In an ion, the number of electrons present can be greater or less than the number of protons, but the number of protons always remains the same. If the number of electrons is greater than the number of protons, then an anion is formed. Anions are negatively charged ions. If the number of electrons is less than the number of protons, then a cation is formed. Cations are positively charged ions.
