Calcium Carbonate is a ternary ionic compound because it has more than two elements.
It is a white to pale yellow brown powder. Back in the day it was used as a weapon, it would be thrown in peoples face and make them blind. Calcium carbonate forms into limestone which is in some counter tops, paper, paints, homes, bridges, toothpastes, cosmetics, and many more.
