Facts about the
Definition of the Element Calcium
The Element Calcium is defined as...
A silvery, moderately hard metallic element that constitutes
approximately 3.5% of the earth's crust and is a basic component
of most animals and plants. It occurs naturally in limestone,
gypsum, and fluorite, and its compounds are used to make plaster,
quicklime, Portland cement, and metallurgic and electronic
materials. The most common uses of Calcium are
in Dairy products ( deficiency can affect bone and teeth formation
- Vitamin D is needed to absorb calcium ), Reducing agent and an
Alloying agent used in the production of alloys.
Interesting Facts
about the Origin and Meaning of the element name Calcium
What are the origins of the word Calcium ?
Originates from the latin word 'calcis' meaning lime.
Facts about the
Classification of the Element Calcium
Calcium is classified as an "Alkaline Earth Metals" which are
located in Group 2 elements of the Periodic Table. An Element
classified as an Alkaline Earth Metals are found in the Earth’s
crust, but not in the elemental form as they are so reactive.
Instead, they are widely distributed in rock structures.

Facts and Info about
the element Argon - IUPAC and the Modern Standardised Periodic Table
The Standardised Periodic Table in use today was agreed by the
International Union of Pure Applied Chemistry, IUPAC, in 1985
which includes the Calcium element. The famous Russian Scientist,
Dimitri Mendeleev, perceived the correct classification method of
"the periodic table" for the 65 elements which were known in his
time. Calcium was discovered by Sir Humphrey Davy in 1808. The Standardised Periodic Table now recognises more periods
and elements than Dimitri Mendeleev knew in his day but still all
fitting into his concept of the "Periodic Table" in which
Calcium is
just one element that can be found.
