Borane (boron hydride)
The term used for any of a group of compounds of boron and hydrogen, many of which can be obtained by the action of acid on magnesium boride (MgB2).

Borax
It is sodium tetraborate decahydrate. Na2B4O710H2O. It is found in nature as tincal (contains about 50% borax) in dried up lakes in Tibet, India, Ceylon and California. It is used in laboratory for Borax bead test

Boron hydrides
They are collectively known as boranes. Their general formula is BnHn+4+ and BnHm+6. They catch fire spontaneously in air. They react with ammonia to form different compounds depending upon the condition.

Boride
A compound of boron, especially one with a more electropositive element.

Bornite
An important ore of copper which is composed of a mixed copper-iron sulphide Cu5FeS4.

Boron
A hard rather brittle metalloid element of group II of the periodic table. It is having the electronic structure 22s2P1. Boron is of low abundance (0.0003%) but the natural minerals occur in very concentrated form as borax (Na2B4O7,10H2O)
And colemanite (Ca2C6O11).
