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. A Calcium Reaction involves a process in which Calcium is mixed with another substance which react to form something else.
 

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 Earths 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 Calcium - 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.
