explain the difference of neutral atom, ions, and isotopes?

Brief Explanations:

A neutral atom has equal number of protons and electrons, resulting in no net charge. Ions are atoms that have gained or lost electrons, giving them a net positive or negative charge. Isotopes are atoms of the same element with the same number of protons but different numbers of neutrons, thus having different atomic masses.

Answer:

A neutral atom is electrically neutral due to equal protons and electrons. Ions are charged due to electron gain or loss. Isotopes of an element vary in neutron - number and atomic mass.
