Colors of Elements in a Flame - Calcium Chloride

Metal salts introduced into a flame give off light characteristic of the metal. Metal ions coine with electrons in the flame and the metal atoms are raised to excited states because of the high flame temperature. Upon returning to the ground state, they give off light (a line spectrum) characteristic of that metal.
