It is produced on a large scale by direct reaction of bromine with excess fluorine at temperatures higher than 150 °C, and on a small scale by the fluorination of potassium bromide at 25 °C. It is a very vigorous fluorinating agent, although chlorine trifluoride is still more violent.
What is the role of bromide in sea life?
The role of biological organobromine compounds in sea life such as algae has been known for much longer. As a pharmaceutical, the simple bromide ion (Br −) has inhibitory effects on the central nervous system, and bromide salts were once a major medical sedative, before replacement by shorter-acting drugs.
What are binary bromides?
Nearly all elements in the periodic table form binary bromides. The exceptions are decidedly in the minority and stem in each case from one of three causes: extreme inertness and reluctance to participate in chemical reactions (the noble gases, with the exception of xenon in the very unstable XeBr 2 ); extreme nuclear instability hampering chemical investigation before decay and transmutation (many of the heaviest elements beyond bismuth ); and having an electronegativity higher than bromine's ( oxygen, nitrogen, fluorine, and chlorine ), so that the resultant binary compounds are formally not bromides but rather oxides, nitrides, fluorides, or chlorides of bromine. (Nonetheless, nitrogen tribromide is named as a bromide as it is analogous to the other nitrogen trihalides.)
How much bromoform is released in the ocean?
The oceans are estimated to release 1–2 million tons of bromoform and 56,000 tons of bromomethane annually. An old qualitative test for the presence of the alkene functional group is that alkenes turn brown aqueous bromine solutions colourless, forming a bromohydrin with some of the dibromoalkane also produced.
What are the two isotopes of bromine?
Bromine has two stable isotopes, 79 Br and 81 Br . These are its only two natural isotopes, with 79 Br making up 51% of natural bromine and 81 Br making up the remaining 49%. Both have nuclear spin 3/2− and thus may be used for nuclear magnetic resonance, although 81 Br is more favourable. The relatively 1:1 distribution of the two isotopes in nature is helpful in identification of bromine containing compounds using mass spectroscopy. Other bromine isotopes are all radioactive, with half-lives too short to occur in nature. Of these, the most important are 80 Br ( t1/2 = 17.7 min), 80m Br ( t1/2 = 4.421 h), and 82 Br ( t1/2 = 35.28 h), which may be produced from the neutron activation of natural bromine. The most stable bromine radioisotope is 77 Br ( t1/2 = 57.04 h). The primary decay mode of isotopes lighter than 79 Br is electron capture to isotopes of selenium; that of isotopes heavier than 81 Br is beta decay to isotopes of krypton; and 80 Br may decay by either mode to stable 80 Se or 80 Kr.

He realised this was a new element and reported it to the French Academy, who confirmed his discovery. When they realised it was chemically similar to chlorine and iodine they proposed the name bromine, based on the Greek word bromos meaning stench.
Why are some uses of bromine declined?
While some uses of bromine have declined because the products made from it are no longer needed , others have been discouraged because of the damage this element could cause to the ozone layer. Volatile organobromine compounds are capable of surviving in the atmosphere long enough to reach the upper ozone layer where their bromine atoms are 50 times more damaging than the chlorine atoms - which are the main threat, coming as they did from the widely used chlorofluorocarbons, the CFCs. The Montreal Protocol which outlawed the CFCs sought also to ban the use of all volatile organobromines by 2010, and this restriction especially applied to the fumigant bromomethane and compounds such as CBrClF 2 which were in fire extinguishers for electrical fires or those in confined spaces.

Introduction to Bromine
The element bromine is a dark red liquid with a noxious odor – one of the only two liquids at room temperature on the periodic table. Chemically, it is very reactive, and is never found pure in nature.
Bromine in the Periodic Table
Bromine, element symbol Br, has an atomic number of thirty-five. One can find bromine, a halogen, in the p-block, group 17, particularly in period 4. Bromine is between chlorine and iodine, and has reactivity between the two. Bromine’s electron configuration is [Ar] 3d10 4s2 4p5.
Toxicity of Bromine
Bromine is incredibly toxic to living organisms and is absorbable through inhalation, consumption, or physical contact. Bromine attacks and corrodes human tissue. In larger doses, bromine can harm the general nervous system, neurotransmitters, or genetic material. Bromine vapor is also an irritant.
Bromine in the Environment
Humans have introduced more bromine into the environment than is naturally occurring, which is harmful to the environment as well as people. When bromine compounds are used in disinfectants in farms or gardens, surface run-off can lead to the accumulation of bromine in natural rivers, ponds, and lakes.
When and How was Bromine Discovered?
Bromine doesn’t have significant applications prior to its discovery in the early nineteenth century. In ancient times, bromine played a role in the coloring of clothing dyes, specifically Tyrian purple, also known as dibromoindigo (6’6 C 16 H 8 Br 2 N 2 O 2 ).
Bromine Chemistry – Compounds, Reactions, Oxidation States
The element bromine has chemical properties in between chlorine and iodine, the halogens flanking bromine in group 17. Bromine is a very chemically reactive metal and thus is never pure in nature: due to its 7 valence electrons and high electron affinity, bromine reacts readily, and violently, with the alkali metals.

Properties
Bromine is the third halogen, being a nonmetal in group 17 of the periodic table. Its properties are thus similar to those of fluorine, chlorine, and iodine, and tend to be intermediate between those of the two neighbouring halogens, chlorine, and iodine. Bromine has the electron configuration [Ar]4s 3d 4p , with the seven electrons in the fourth and outermost shell acting as its valence electrons. Like all halogens, it is thus one electron short of a full octet, and is hence a strong oxidising age…
Chemistry and compounds
Bromine is intermediate in reactivity between chlorine and iodine, and is one of the most reactive elements. Bond energies to bromine tend to be lower than those to chlorine but higher than those to iodine, and bromine is a weaker oxidising agent than chlorine but a stronger one than iodine. This can be seen from the standard electrode potentials of the X2/X couples (F, +2.866 V; Cl, +1.…
Occurrence and production
Bromine is significantly less abundant in the crust than fluorine or chlorine, comprising only 2.5 parts per million of the Earth's crustal rocks, and then only as bromide salts. It is the forty-sixth most abundant element in Earth's crust. It is significantly more abundant in the oceans, resulting from long-term leaching. There, it makes up 65 parts per million, corresponding to a ratio of about one b…
Applications
