CAL-CI-UM

Chem4Kids Scientist Guy with Spiked Hair
You must have heard of calcium before. Calcium (Ca) is an important element that helps your bones stay strong and able to support your weight. Your nervous system also uses calcium to help transmit impulses through your body.

Humans have known about calcium and calcium containing compounds since before the Greeks and Romans. Romans used lime in their concrete and gave it the name "Calx." That name was used when Davy was the first chemist to isolate pure calcium in 1808. When you think of calcium, you might think of a white powder, but when purified, calcium is a hard silver-colored metal.

You will find calcium in the second column of the period table with other elements including beryllium and magnesium. The elements in that column make up the alkali earth metal family.
