Element number 5 is Boron, and its symbol is B. Its five electrons are arranged as 2, 3.

This element is a non metal. It is a hard black solid melting above 2000°C. It is present in minerals such as Borax (Na2B4O7) from which it gets its name. It is never found in elemental form.

Its compounds are used as additives to make glass resistant to heat (for example Pyrex), high energy fuels, sports rackets, eye disinfectant and for vulcanising rubber.

Boron is also used as a catalyst. A catalyst is a substance that speeds up or facilitates a chemical reaction without being used up.
