an atom or goup of atoms (radical) carrying an electrical charge. It is contrasted with neutral atoms or molecules, and free radicals. Certain compounds, such as sodium chloride, are composed of complementary ions in the solid (crystalline) as well as in solution. Others, notably acids such as hydrogen chloride, may occur as neutral molecules in the pure liquid or gas forms, and ionize almost completely in dilute aqueous solutions. In solutions (as in water) ions are frequently bound non-covalently with the molecules of solvent, and in that case are said to be solvated. According to the electrolytic dissociation theory, the molecules of electrolytes are divided into ions by water and other solvents. An ion consists of one or more atoms and carries one unit charges of electricity, 3.4 x 10-10 electrostatic units, or a multiple of this. Those which are positively electrified (hydrogen and the metals) are called cations; negative ions (hydroxyl and acidic atoms or groups) are called anions.

the process of converting neutral atoms or molecules into ions. The process may occur by dissolving an ionic substance in a dissociating solvent, such as water, or by adding or subtracting an electron to or from an atom or molecule. The latter process occurs, for example, in an electron beam in a mass spectrometer and by interaction of substances with ionizing radiation.
To convert (an atom or molecule) into ions, e. g. by dissolving in water, by reaction with acid or alkali, or by interaction with ionizing radiation. See ionization.

A compound that enhances transport of ions across cellular membranes, by binding them and carrying them across. As a class ionophores tend to be lipophilic in nature; each compound is usually specific for one or a small number of ions.
