toc =Quick Facts:=
 * Bromine's most common state at earth temperatures is a liquid.
 * There are about 10 to the 16th power tons of Bromine, but this element is found in low concentrations. Bromine is not rare.
 * Bromine can also be found in the Ocean
 * There are two natural isotopes of Bromine. Bromine-79 and Bromine-81
 * Sixteen known isotopes are radioactive and unnatural. None of these isotopes have significant commercial use.
 * The modern day usages of Bromine are flame retardants, an important ingredient in pesticides, and is used in drilling wells.
 * Bromine can also be used as an alternate to Chlorine.
