|Atomic mass||40.1 amu| |Number of Stable Isotopes||6| |Date of
discovery||1808| |Name of discoverer||Sir Humphrey Davy| |Name
origin||From the Latin calx (limestone)| |Uses||Calcium is one
of the primary elements in bones, shells, etc. Taking calcium
internally can promote bone growth.| |Obtained from||Chalk,
limestone, marble.| Calcium is a very important element to human
physiology, as calcium-phosphate salts form the basis for the
creation of bones. It is also a critical cellular component in
all organisms, and in animals serves roles of particular
importance in blood, the cardiovascular system, and the nervous
system. Consuming too much calcium can lead to kidney stones,
which are typically composed of calcium deposits. Calcium in its
pure form is referred to as "the white element" and must be kept
isolated from air. |Periodic Table of the Elements|
