This is why it is called the Dead Sea. Two naturally existing isotopes of bromine exist, bromine and bromine Isotopes are two or more forms of an element. Isotopes differ from each other according to their mass number.

The number written to the right of the element's name is the mass number. The mass number represents the number of protons plus neutrons in the nucleus of an atom of the element. The number of protons determines the element, but the number of neutrons in the atom of any one element can vary. Each variation is an isotope. At least 16 radioactive isotopes of bromine are known also. A radioactive isotope is one that breaks apart and gives off some form of radiation.

Radioactive isotopes are produced when very small particles are fired at atoms. These particles stick in the atoms and make them radioactive. The method used by Lowig and Balard to collect bromine continues to be used today. Chlorine is added to seawater containing sodium bromide or potassium bromide. Chlorine is more active than bromine and replaces bromine in the reaction:. The most important use of bromine today is in making flame retardant materials. Many materials used in making clothing, carpets, curtains, and drapes are flammable, and if a flame touches them, they burn very quickly.

Chemists have learned how to make materials more resistant to fires by soaking them in a bromine compound. The compound coats the fibers of the material. The bromine compound can also be chemically incorporated into the material. The bromine compounds used in flame retardants are often complicated. However, this compound has been found to be a carcinogen cancer-causing substance.

Its use, therefore, has been severely restricted. About 20 percent of all bromine is used in drilling wells. Calcium bromide CaBr 2 , sodium bromide NaBr , or zinc bromide ZnBr 2 are added to the well to increase the efficiency of the drilling process. Bromine is also important in the manufacture of pesticides, chemicals used to kill pests. Methyl bromide CH 3 Br has been used for years to treat crop lands. Methyl bromide is sprayed on the surface or injected directly into the ground.

Some methyl bromide always evaporates into the air where it damages the ozone layer. Ozone O 3 gas filters out a portion of the ultraviolet UV radiation from the sun. UV radiation causes skin cancer, sunburn, and damage to plants and fragile organisms. Worldwide production of methyl bromide will end in because of its effect on the ozone layer. The United States plans to stop production of the compound even earlier.

Farmers believe nothing works as well as methyl bromide in eliminating certain pests. They are concerned that crop production will suffer if methyl bromide is banned. Ethylene dibromide C 2 H 4 Br 2 is a bromide compound added to leaded gasoline. The lead in "leaded gasoline" is tetraethyl lead Pb C 2 H 5 4. It helps fuels burn more cleanly and keeps car engines from "knocking. But leaded gasoline gives off free lead as it burns.

Free lead is a very toxic element that causes damage to the nervous system. Ethylene dibromide is added to react with free lead and convert it to a safe compound.

It is defined as being the charge that an atom would have if all bonds were ionic. Uncombined elements have an oxidation state of 0. The sum of the oxidation states within a compound or ion must equal the overall charge.

Data for this section been provided by the British Geological Survey. An integrated supply risk index from 1 very low risk to 10 very high risk. This is calculated by combining the scores for crustal abundance, reserve distribution, production concentration, substitutability, recycling rate and political stability scores.

The percentage of a commodity which is recycled. A higher recycling rate may reduce risk to supply. The availability of suitable substitutes for a given commodity. The percentage of an element produced in the top producing country.

The higher the value, the larger risk there is to supply. The percentage of the world reserves located in the country with the largest reserves. A percentile rank for the political stability of the top producing country, derived from World Bank governance indicators. A percentile rank for the political stability of the country with the largest reserves, derived from World Bank governance indicators.

Specific heat capacity is the amount of energy needed to change the temperature of a kilogram of a substance by 1 K. A measure of the stiffness of a substance. It provides a measure of how difficult it is to extend a material, with a value given by the ratio of tensile strength to tensile strain. A measure of how difficult it is to deform a material.

It is given by the ratio of the shear stress to the shear strain. A measure of how difficult it is to compress a substance. It is given by the ratio of the pressure on a body to the fractional decrease in volume. A measure of the propensity of a substance to evaporate.

It is defined as the equilibrium pressure exerted by the gas produced above a substance in a closed system. This Site has been carefully prepared for your visit, and we ask you to honour and agree to the following terms and conditions when using this Site.

Bromine is a deep-red, oily liquid with a sharp smell. It is toxic. Bromine is used in many areas such as agricultural chemicals, dyestuffs, insecticides, pharmaceuticals and chemical intermediates. Some uses are being phased out for environmental reasons, but new uses continue to be found. Bromine compounds can be used as flame retardants.

They are added to furniture foam, plastic casings for electronics and textiles to make them less flammable. However, the use of bromine as a flame retardant has been phased out in the USA because of toxicity concerns. Organobromides are used in halon fire extinguishers that are used to fight fires in places like museums, aeroplanes and tanks. Silver bromide is a chemical used in film photography. Before leaded fuels were phased out, bromine was used to prepare 1,2-di-bromoethane, which was an anti-knock agent.

Biological role. Bromine is present in small amounts, as bromide, in all living things. However, it has no known biological role in humans. Bromine has an irritating effect on the eyes and throat, and produces painful sores when in contact with the skin. Natural abundance.

Bromine is extracted by electrolysis from natural bromine-rich brine deposits in the USA, Israel and China. It was the first element to be extracted from seawater, but this is now only economically viable at the Dead Sea, Israel, which is particularly rich in bromide up to 0.

Elements and Periodic Table History. He took the concentrated residue which remained after most of the brine had evaporated and passed chlorine gas into it. In so doing he liberated an orange-red liquid which he deduced was a new element.

He was asked to produce more of it, and while he was doing so Balard published his results and so became known at its discoverer. Atomic data. Bond enthalpies. Glossary Common oxidation states The oxidation state of an atom is a measure of the degree of oxidation of an atom.
