Calcium

Calcium metal is used as a reducing agent in preparing other metals such as thorium and uranium. It is also used as an alloying agent for aluminium, beryllium, copper, lead and magnesium alloys.

Atomic Number: 20Number of electrons: 20Atomic Mass: 40.078Boiling/Melting Point: 2703°F/1548°FNumber of protons: 20Element category: Alkaline Earth MetalsNumber of neutrons: 20Period/Group: 4/2

Calcium metal was not isolated until 1808. Sir Humphry Davy was able to isolate the metal. He did this by the electrolysis of a mixture of lime and mercuric oxide (HgO). Calcium metal was not available in large scale until the beginning of the 20th century. The name is derived from the Latin 'calx' meaning lime.

Basic Info:

~Calcium is the 5th most abundant element in the Earth's crust~Calcium isn't found free in nature, but it can be purified into a soft silvery-white alkaline earth metal.~The element is essential for animal and plant nutrition.

Interesting Facts:

Oxidation: Used as a deoxidizer in steelIsotopes: SixCompounds: Compounds include limestone, marble, and gypsumFlammability: When heated in air or in oxygen it ignitesReactivity: with waterReacts with cold water rapidly at first, but the reaction is then slowed due to the formation of a film of Calcium hydroxide - Ca(OH)2.Reactivity with acids: Highly reactive
