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).
