Bromine was discovered by two two chemists Antoine Balard, and Carl Jacob Lowig sometime between 1825 and 1826.Both discovered it by way of using salt. Balard found Bromine in it Bromide salt state. Lowig found it in its elemental form, by combining Bromide salts and Chlorine. It was not massly produced until the 1860's. It was given the name Bromine by a French Chemist Joseph Lussac, because of the foul odor.

Properties
Bromine is a dangurosly dense fast moving reddish-brown liquid. It gives off a very toxic vapour that has a nasty smell. Bromine closely resembles Chlorine but it is not as reactive as Chlorine is. Bromine water is used to find unsaturated compounds. Bromine has many properties from physical to energy. Bromine is the only nonmetallic element that is a liquid. It is alos very soluble in organic solvents and water. It will combine with almost any element. It also has a type of bleaching affect, to human skin or clothes.
Occurrences
Bromine is an interesting element because it cant befound in its element form naturally. Instead it is found in compounds with other elements. Those create Bromides, in turn they are used to make commercial products.Bromine is abundant in nature as bromide salts or as organobromine compounds, which are produced by many types or marine organisms. A couple decades ago governments started to introduce organic Bromines into the enviroment. Because they are not natural they can cause serious health issues to human and the enviroment. Sea water contains a vast amount of Bromine. There is a much higher concentration of it in inland seas and lakes.
Uses
Bromine is used in many ways in todays society. Some of these include making fire retardent materials, medicines, and in water purification compoundss. It is also used in many other things, but those are some of the main ones. Bromine has been used to disinfect swimming pools since WW 2. Bromine has been used in some cleaning of public water towers. There needs to be a large amount of Bromine to make the cleaning effective. Since the early 30s the U.S. has used Bromine to dienfect water and the containers of water.
Health
Bromine is very hazardous to humans and animals. Depending on how much we come in comtact with abd what state it is in. It is also hazardous to the enviroment. There are some measures that we can use to protect against Bromines deadly effect. Even though it is used in water. When it is not in that sate it is very dangerous.If you breathe in Bromine you will have long term lung problems. Other effects can be caused by low blood pressure. The main organs that Bromine affect are: Respiratory, skin, eyes, and CNS.
