The valence of an element is the maximum number of hydrogen or chlorine atoms that can combine with an atom of the element.Carbonis in Group 14 of the Periodic Table, so acarbonatom has four valence electrons. It can also bond with four atoms of chlorine. The prefix tetra- means four, socarbon is tetravalent.

Because of its two unique property

* CATENATION - carbon can make bond with another carbon atom

*TETRAVALENT- it can react with element having valency four and less than four

Sodium carbonate (washing soda) isusedin glass, soap, and paper industries.

It isusedin the manufacture of sodium compounds such as Borax.

Sodium hydrogen carbonate is also ingredient in antacids. ...

It is alsousedinsoda-acid fire extinguishers.

Carbon forms largeno. ofcompoundsdue to the following reasons: Catenation: The property ofcarbonelement due to which its atoms can join one another toformlongcarbonchains is called catenation. Tetravalency:Carbonhas a valency of four.

main reason is that carbon have two special characteristics which are catenation and tetravalency.
