This video explains ionic bonding. An ionic compound is made up of charged particles, called ions. It has a giant lattice structure, with strong electrostatic forces of attraction.

A small piece of sodium metal is placed in a flask of chlorine gas. A little water helps expose the sodium so it can react with the chlorine gas. The reaction releases a lot of heat as the ionic ...
