How was bromine discovered?
Antoine-Jérôme Balard
History. Antoine-Jérôme Balard discovered bromine while investigating some salty water from Montpellier, France. He took the concentrated residue which remained after most of the brine had evaporated and passed chlorine gas into it. In so doing he liberated an orange-red liquid which he deduced was a new element.
Who discovered bromine and iodine?
Antoine Jérôme Balard
Its properties are intermediate between those of chlorine and iodine. Isolated independently by two chemists, Carl Jacob Löwig (in 1825) and Antoine Jérôme Balard (in 1826), its name was derived from the Ancient Greek βρῶμος (“stench”), referring to its sharp and disagreeable smell.
Why is bromine so important?
Bromine, chemical symbol Br and atomic number 35, is a reddish-brown liquid that is being used in key applicationssuch as water treatment, the reduction of mercury emissions, fire safety, energy storage and generation, production of pharmaceuticals and enhanced quality rubber.
What is the use of bromine?
Products containing bromine are used in agriculture and sanitation and as fire retardants (chemicals that help prevent things from catching fire). Some bromine-containing compounds were historically used as sedatives (drugs that can make people calm or sleepy).

Calcium/Discoverers
Calcium, 20 In 1808 calcium was first isolated by Sir Humphry Davy, a chemist, inventor and at the time Britain’s leading scientist. He conducted many experiments to reduce moist lime by electrolysis, similarly to producing sodium and potassium, with often unsuccessful results.
What is the old name of iron?
ferrum
The Latin name for iron is ferrum, which is the source of its atomic symbol, Fe. The word iron is from an Anglo-Saxon word, iren. The word iron is possibly derived from earlier words meaning “holy metal” because it was used to make the swords used in the Crusades, according to WebElements.
What is unique about bromine?
Bromine is the only nonmetallic element that is liquid at ordinary temperatures. It is a dense, reddish-brown liquid which evaporates easily at room temperature to a red vapor with a strong, chlorine-like odor. Bromine is less reactive than chlorine or fluorine but more reactive than iodine.
What is the group number of bromine?
Bromine is the third –lightest element in the halogen family. It is a chemical element and it is a member of group 17 and period 4 in the periodic table. Atomic number of bromine is 35 and it is indicated by symbol is Br. Br belongs to the halogen family.
What is bromine found in?
Bromine is found naturally in the earth’s crust and in seawater in various chemical forms. Bromine can also be found as an alternative to chlorine in swimming pools.
What are the chemical properties of bromine?
Bromine is a chemical element with symbol Br and atomic number 35. It is the third-lightest halogen, and is a fuming red-brown liquid at room temperature that evaporates readily to form a similarly coloured gas. Its properties are thus intermediate between those of chlorine and iodine.
