Bromine (Br) is a chemical element that was originally isolated by two chemists Carl Jacob Lowig and Antoine Jerome Balard. Bromine is a reddish-brown liquid at room temperature. Bromine cannot occur freely in nature, and is actually rarer than over 75 percent of the elements found in the Earth’s crust. Currently, Bromine is most easily able to be extracted from brine pools. Bromine gives off a very strong smell that closely resembles the smell of chlorine. Interestingly enough, Bromine is one of only two elements on the periodic table that remains a liquid at room temperature. Bromine also binds easily with a lot of other elements, and is only slightly soluble in water.
