Top 10 interesting facts about Bromine

  • Bromine was discovered in 1826 by Antoine J. Balard. Its name drives from the Greek word "bromos" (which means stench).
  • Bromine's melting point is at -7.2 C (265.95 K, 19.04 F) and its boiling point is at 58.78 C (331.93 K, 137.804 F).
  • Elemental bromine is a dark red liquid (at room temperature) that evaporates easily.
  • Bromine is a very toxic and corrosive element similar to chlorine.
  • Bromine does not occur freely in nature.
  • Bromine is extracted from the ocean water.
  • Bromine is mostly produced in the USA, Israel, and China.
  • Over 500,000 tones of bromine are produced annually, a huge amount considering that it is an element less abundant in Earth's crust than three thirds of the chemical elements.
  • More than a half of bromine production is used as fire retardant.
  • More than 23 isotopes of bromine are known but only two are stable: 79-Br and 81-Br.
