Bromine facts are very harmful to the atmosphere. According to Chemical, bromine atoms are 40 to 100 times more devastating in the ozone layer than chlorine atoms. Half of the loss of ozone over Antarctica is with bromine.
Methyl bromide used as a fumigant is the largest source of the ozone layer destroying bromine. About 30% of bromine in the atmosphere comes from human activities, the rest is natural.
The physical and chemical properties of bromine are unique compared to other elements. A few of these important features of this element are the following.
Elemental bromine can be identified as a thick liquid with a red-brown color and strong odor.
Bromine facts occur in nature, but not in free form. It is usually available as a bromine salt. These salts are well soluble in water and accumulate in various water bodies.
For this reason, the main source of bromine is seawater, from which it isextract for commercial purposes. The United States, Israel, and China are the largest producers in the amount of this chemical element.
Its atomic number is 35 and its atomic mass is 79.90. The number of electrons per shield is 2, 8, 18 and 7.
Bromine dissolves in water but has a higher solubility in various organic solvents, such as methanol, carbon disulfide, aliphatic alcohols, acetic acid and the like.
Compared to other halogens such as fluorine or chlorine, it has a slightly less reactive nature. Due to its strong oxidizing properties, it reacts with metals quite vigorously, especially if it takes place in the presence of water, forming bromide salts. It also shows high reactivity to organic compounds, especially in favorable lighting conditions.
Two scientists working independently discovered bromine in the 1820s, according to Peter van der Krogt, a Dutch historian.
Carl Löwig, a German chemistry student studying under the German chemist Leopold Gmelin, isolated liquid bromine in 1825, taking a sample of water from the source of salt in Bad Kreuznach and adding chlorine, according to Chemicool. After shaking the solution with ether, Löwig discovered the reddish substance in solution and separated it by evaporation of the ether.
This scientist, Antoine-Jérôme Balard. A French chemist, isolated bromine when he studied brown seaweed known as a focus, according to Peter van der Krogt.
At first, he thought it was a chlorine or iodine compound, and when he could not isolate any of these elements, he suggested that he actually found a new element. Ballard suggested the name murideo, from the Latin word “maria” or brine, for his new element.
