100 Interesting Facts About Bromine

Facts About Bromine: Bromine word is derived from the Greek word bromos, meaning goat's smell. It is a chemical element with the symbol Br, atomic number 35, and atomic weight 79.904. These are included in the halogen group. In 1825-26 this element was discovered by two different scientists. Karl Jacob Loewing and Antoine Jerome Ballard. In pure elemental form, bromine is a fuming, toxic, highly concentrated reddish-brown liquid at room temperature. Its properties are between those of chlorine and iodine. Pure bromine does not occur in nature, but occurs in crystalline form as colorless water-soluble halide salts that look like salts.

Strange Facts About Bromine

  • By now, you possibly know that bromine is a name derived from the Greek word ‘Bromos’, which means stench. However, did you know that bromine smells like he-goat and hence the name.
  • Bromine is a chemical element, no surprises there! In the periodic table, it is represented by a Br symbol. 35 makes for bromine’s atomic number, while 79.904 makes for its atomic mass.
  • At high temperatures, organobromine compounds can be easily converted into free bromine atoms. This is a process, which is very effective in terminating free radical chemical chain reactions.
  • Bromine is named after the Greek word bromos meaning stench because bromine smells... "stinky." It's a sharp, acrid odor that's hard to describe, but many people know the smell from the element's use in swimming pools.
  • Both Carl Jacob Löwig and Antoine Jérôme Balard are considered discovers of bromine. Löwig technically isolated it before Balard, but due to a delayed publication Balard was the first to publish the discovery of bromine.
  • Bromide compounds used to be used as sedatives and anticonvulsants. Specifically, sodium bromide and potassium bromide were used in the 19th and 20th century until they were replaced by chloral hydrate, which was in turn replaced by barbituates and other drugs.
  • When expressed in °Kelvin, bromine melts at 265.9. When expressed in the same scale, bromine boils at 331.9. Now that you know the melting and boiling point of bromine, it might help you to know a little about the density of the element. Bromine comes with a density (g/cc) of 3.12.
  • As for the uses of bromine, there are quite a few. Bromine is used extensively in the production of gasoline antiknock mixtures, dyes, fumigants and photographic chemicals. Bromine, apart from being used for all of the above-mentioned purposes, is also used in the making of Brominated vegetable oil and certain medicines.
  • For commercial purposes, bromine is extracted from brine pools that are found in the United States of America and Israel, making it hardly surprising that these two countries specialize in the production of Bromine. Apart from the United States of America and Israel, China too enjoys an abundance of brine pools, making it a very important country as far as the production of bromine is concerned.
  • Bromine is used in many fire retardant compounds. When brominated compounds burn, hydrobromic acid is produced. The acid acts as a flame retardant by interfering with the oxidation reaction of combustion. Nontoxic halomethane compounds, such as bromochloromethane and bromotrifluoromethane, are used in submarines and spacecraft. However, they are not generally useful because they are expensive and because they damage the ozone layer.
  • Bromine was nearly discovered by two other chemists before Antoine Jerome Balard published his discovery. The first was in 1825 by the German chemist Justus von Liebig. He was sent a sample of salt water to analyze from a nearby town. He thought the brown liquid he separated from the salt water was a simple mixture of iodine and chlorine. After he learned of Balard's discovery, he went back and checked. His liquid was the newly discovered bromine. The other discoverer was a chemistry student named Carl Loewig. He separated the same brown liquid in 1825 from another sample of salt water. His professor asked him to prepare more of the brown liquid for further testing and soon learned of Balard's bromine.
