Its salts are found in the crust at about . 4 parts per million. Bromine is only the 64th most common element on Earth. It is more rare than three quarters of the elements that comprise the Earth's crust
bromine is commonly found in highly un-reactive bromide salts - in much the same way that the poisonous green gas chlorine is commonly found in boring sodium chloride, table salt. ...
