    Calcium's atomic number is 20 and its symbol is Ca. Calcium is a dull grey metal that is often associated with milk and healthy bones. While it is true that calcium plays a major role in bone health, pure calcium metal would be a major hazard to ingest since it readily reacts with water creating heat and hydrogen gas. Calcium is the third most abundant metal in the earth's crust behind iron and aluminum. Tens of thousands of tons of calcium are mined every year in the form of fossils and minerals such as limestone. The sample of calcium in our element cube displays is pure calcium pellets loosely encapsulated in a glass ampule.
