Ionic bonds are atomic bonds created by the attraction of two differently charged ions. The bond is typically between a metal and a non-metal. The structure of the bond is rigid, strong and often crystalline and solid. Ionic bonds also melt at high temperatures. Dissolved in water, ionic bonds are aqueous, that is, they can conduct. Mar 18, 2009 · With a little thought, I made a sudden epiphany recently, in noticing that ammonium chloride (NH4Cl), can actually be split into two separate chemicals, NH3, and HCl. I thought of various methods, how this can be done, however, in ionising, the salt does not form the compounds above, but rather ammonium ion (NH4+) and chlorine ion (Cl-).
