Whats the opposite of sis-yours? - Bromine: Kurtis Chong - 8th Grade Science mrs. Bryan

Bromine (Br) was discovered in 1826 by Antoine-Jerome Balard while he was investigating salty water from Montpellier, France. He took the concentrated residue which remained after most of the water had evaporated and passed chlorine gas into it. During this process he discovered an orange-red liquid which was "Bromine". It name is derived from the Greek word "Bromos" which means stench.

  • The atomic number of Bromine is 35
  • The atomic mass of Bromine is 79.904
  • Bromine has 35 Protons, 45 Neutrons, and 35 Electrons
  • Bromine has 2 different stable isotopes being Br-79 & Br-81; Br-79 with a natural abundance of 50.69% and Br-81 having a natural abundance of 49.31%

Bromine is extracted by electrolysis (chemical decomposition produced by passing an electric current through a liquid or solution containing ions) from natural bromine-rich deposits in the USA, Israel, and China. It was the first element to be extracted from seawater, yet today the only economically viable and natural source is at the Dead Sea, Israel, having up to 0.5%. It has also been discovered in the Earth's Crust.

Bromine compounds are often used as flame retardants. They are added to things such as furniture foam and plastic casings to make them less flammable. In the USA because of exposure to toxicity concerns, they are no longer allowed as a flame retardant.

Bromine is used as a Water Purification method. Bromine is used in pools and drinking water. In fact, is it a very important element in the purification of water, as it disinfects most or all of the water. It is often used as an alternative to chlorine.

Bromine is one of the items in drinks such as Gatorade, Powerade, Mountain Dew, Fanta, and in 10% of all sodas in the USA, yet it is banned throughout places such as Japan and Europe. This chemical in these drinks is a Bromine compound known as BVO, Brominated Vegetable Oil, derived from corn or soy and bonded with Bromine. It is used in these beverages as an emulsifier, to prevent the flavorings from separating and floating to the surface. Recently, Coca-Cola and Pepsi agreed to stop using BVO due to the fact that Bromine is a toxic endocrine disruptor that can damage your thyroid and lead to cancer, infertility, schizophrenia, and many other serious diseases.

  • Fun Fact: Bromine was a component of World War I era poison gas.
  • Scientific Fact: Along with mercury, bromine is one of two elements found to be a liquid at room temperature.
