An ion is an atom that has acquired a net electrical charge. An atom is uncharged because its number of electrons and protons are equal, and the magnitude of the negative charge of an electron is equal to the magnitude of the positive charge of a proton. An ion has the same number of protons as the atom from which it formed, but a different number of electrons. A negative ion (or anion) has one or more extra electrons, while a positive ion (or cation) has one or more electrons missing. Atoms give up or accept electrons to become ions because it leaves them with a full and therefore stable outer electron shell.

an atom is basically the simplest unit of matter. Everything is made up of it. Ions are formed when electrons in shell of the atom is either stipped off or electrons are added onto it. Atoms have got no charge while ions have and could either be positive or negative (that's why there are positive and negative ions)

Hi. An ion IS an atom but with one or more electrons stripped off.
