Description and uses
Bromine is the 35th element of the periodic table. It was discovered in 1826, when Carl Löwig evaporated the water away from a natural spring containing bromine,
which is commonly found in seawater in the form of potassium bromide. It has few uses due to its toxicity.
Bromine's main use is as a flame retardant, as bromine is a good insulator, and can protect flammable items from catching fire. Examples of this include in
electronics and in furniture.
Bromine has 2 naturally occurring isotopes, being 79Br and 81Br. They have very similar abundances, with 79Br being slightly
more common, taking up around 51% of all bromine atoms, and 81Br taking up the remaining 49%
