In molten or aqueous states, ions are no longer held in fixed positions, and can move around to conduct electricity. Do not conduct electricity in solid state but can conduct electricity in molten or aqueous states: In solid state, the ions are held in fixed positions, and are unable to move to conduct electricity.Crystalline solid with regular shape: Ions are arranged with cations and anions alternating.Exist as solids at r.t.p: Large amount of energy required to break strong strong electrostatic forces of attraction between oppositely charged ions in the crystal lattice structure.High melting point and boiling point: Large amount of energy required to break strong strong electrostatic forces of attraction between oppositely charged ions in the crystal lattice structure.The oppositely charged ions vibrate in fixed positions in a giant crystal lattice with strong electrostatic forces of attraction between oppositely charged ions throughout the structure.that there are 8 electrons in the outermost shell after bonding except for ions formed by H, Li and Be which will have 2 electrons. ![]() that there are different symbols for the electrons in a non-metal ion.the charges are shown : + for metal ion and – for non-metal ion. ![]()
