Home Dictionary Name: ionIon
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 34 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...

All of the parties to the cases must agree to accept the outcome of the test case as bi...
