Bromine is the only non-metallic element that is liquid at room temperature and standard pressure. It is a red liquid that easily evaporates and smells. Bromine is approximately 3,12 times heavier than water. At temperatures of 58,8 °C it becomes gaseous & at –7,3 °C and lower temperatures it is a solid.

Bromine is a bleach. It is poisonous in fluid form and bromine vapor is destructive of human skin, eyes and respiratory tract. It causes serious burns. A concentration of 1 ppm can cause eye watering and when inhalation of concentrations below 10 ppm occurs, one starts to cough and the respiratory tracts are irritated.
