Detailed explanation-1: -An ion is a charged atom or molecule. It is charged because the number of electrons do not equal the number of protons in the atom or molecule. An atom can acquire a positive charge or a negative charge depending on whether the number of electrons in an atom is greater or less then the number of protons in the atom.

Detailed explanation-2: -By definition, an ion is an electrically charged particle produced by either removing electrons from a neutral atom to give a positive ion or adding electrons to a neutral atom to give a negative ion.

Detailed explanation-3: -An ion is an atom or group of atoms that has an electric charge. Ions with a positive charge are called cations. Ions with a negative charge are called anions. Many normal substances exist in the body as ions.

Detailed explanation-4: -In either case, they become ions. Ions are atoms that have a positive or negative charge because they have unequal numbers of protons and electrons. If atoms lose electrons, they become positive ions or cations. If atoms gain electrons, they become negative ions or anions.

Detailed explanation-5: -An ion is an atom that has lost or gained electrons resulting in a positive charge (from losing electrons) or a negative charge (from gaining electrons). Answer 4: An atom, is, by definition, neutral, so the total charge will always be zero. Any charged atom is called an ion.
