INTRODUCTION
Bromine is a poisonous element that at room temperature is a dark, reddish-brown liquid.It causes sores that heals very slow, when it comes in contact with the skin.
It has a lot of similarity in its chemical properties to chlorine, with which it is almost invariably associated, that it was not recognized as a separate element until 1826, when it was discovered.

ECONOMIC IMPORTANCE
* Bromine is used in the preparation of certain dyes and of dibromoethane, a constituent of antiknock fluid for leaded gasoline.
* It is used in photographic compounds and in natural gas and oil production.
* Potassium bromide is used as sedative, and as an anticonvulsant epilepsy.
* Bromo compounds may be included in the polimerization when making acrylic and polyester fibres.
