What is a difference between an isotope and a ion
An ion is an atom that has anything but a neutral charge (it can either be positive or negative). An isotope, on the other hand, occurs when there is a deficiency in the number of neutrons in an atom. This does not affect the overall charge.
An isotope has two or more copies of a component whereby the atoms have the corresponding amount of protons. While ion is a combination of atoms exhibiting electrical explosives such as the sodium and chlorine atoms in a seasoning extract.
