Bromine

Located at Group 17 and Period 4 of the periodic table is the only non - metallic element that is liquid at ordinary temperatures. This is Bromine.

First discovered by Carl Löwig in 1829, but at the same time was discovered by Antoine Jérôme Balard independently and first isolated by Carl Löwig using a solution of the mineral salt saturated with Chlorine and then extracted Bromine with diethyl ether from a mineral water spring from his hometown Bad Kreuznach in 1825.

Carl Jacob Löwig

The story was complicated, you know, the fact that both chemist discover Bromine at once. In detail, Bromine was first produced by Carl Löwig, a chemistry student by using a solution of the mineral salt saturated with Chlorine.

Antoine Jérôme Balard

On the other side, Antoine Jérôme Balard first discovered it by taking a concentrated residue which remained after most of the brine had evaporated and passed Chlorine gas into it. He sent an account of his findings to the French Academy's journal in 1826.

Its only first isolated by Carl Löwig in 1825. Now you might be wondering why isolating is earlier than discovery : This is because that earlier, Carl Löwig has already isolated Bromine, its just that he did not notice.

Until Antoine Jérôme Balard reported his discovery only then he realized he had isolated a new element. Which is why after that he only claimed that he knew how to isolate Bromine earlier.

Besides, being the 44th most common elements in the earth's crust, Bromine can be found in 2.4 parts per million. So, Bromine can be said to be very common.

  Toxic Symbol

How Bromine got its name?

Bromine got its name from the Greek word bromos, meaning stench, because of its sharp smell. It's named by Antoine Jérôme Balard for his credit of discovery.

Uses

Sodium Bromide ( Bromine Salt ) are used as an disinfectant and are sold in stores. Besides disinfectant, Bromine can also be used to do agriculture pesticides. So, you can say that Bromine is very toxic.
