calcium | Definition, Properties, & Compounds | Britannica

Calcium constitutes 3.64 percent of Earth’s crust and 8 percent of the Moon’s crust, and its cosmic abundance is estimated at 4.9 × 10 4 atoms (on a scale where the abundance of silicon is 10 6 atoms). As calcite (calcium carbonate), it occurs on Earth in limestone, chalk, marble, dolomite, eggshells, pearls, coral, stalactites, stalagmites, and the shells of many marine animals.

Calcium Element: (Properties, Uses, and Discovery) - …

Adding some calcium into aluminum metal makes an alloy that is stronger than aluminum alone and improves bearings strength. Hydrogen can be stored in calcium metal because it reacts with calcium to form calcium hydrides, and extracting hydrogen gas back from the calcium is very easy.
