Metallic Character - THE PERIODIC TABLE OF ELEMENTS

Metallic character is a name given to elements that are metals and their chemical properties. The metallic character of an element decreases as you move from left to right or bottom to top of the periodic table. This is because atoms have a better ability to gain electrons to fill a valence shell than lose them to and an unfilled shell.

Calcium - Element information, properties and uses

Calcium was named after the Latin term calx meaning lime, and is a reactive silvery metallic element found in Group 2 of the periodic table. It was first isolated in 1808 in England when Sir Humphry Davy electrolyzed a mixture of lime and mercuric oxide. Today we obtain calcium through the electrolysis of a fused salt such as calcium chloride.
