Beryllium Chemical Properties (23 Facts You Should Know)

Beryllium belongs to the category of alkaline (earth) metals. Even though it is brittle but is strong enough and lightweight. Let us study some facts about it.

Beryllium has a hexagonal close packed crystal structure. In appearance it is a white grey colored solid (at room temperature) and belongs to the s-block of elements. The extraction of this element is carried out from beryl (consisting of beryllium and aluminium silicate).

Extraction process is quite difficult as the bonding between the oxygen and beryllium atom is very strong. Let us study some properties of beryllium like melting and boiling point, energies of ionization, etc.
