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).
Top 8 interesting facts about bromine
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 500000 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.
