(leading to high volatility) thanks to their diatomic molecular structure.[25] The halogens darken in colour as the group is descended: fluorine is a very pale yellow gas, chlorine is greenish-yellow, and bromine is a reddish-brown volatile liquid that melts at −7.2 °C and boils at ...
Bromine, or dibromine, Br2, is the elemental form of bromine, Br. Free bromine does not occur in nature; instead, bromine is usually found in the form of mineralhalidesalts. At ambient temperature, bromine is a fuming, red-brown liquid that is corrosive, toxic and has a highly offensive...
