Notes:
Calcium is just behind aluminum and iron in the list of abundant metals, and makes up 3% of the Earth's crust. Calcium Carbonate can be found as limestone, marble, chalk seashells, and calcite. It is found as dolomite when combined with magnesium. Calcium is a good reducing agent and forms heavy hydroxide coats with contact with moist air.
