Where can bromine be found?
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. Products containing bromine are used in agriculture and sanitation and as fire retardants (chemicals that help prevent things from catching fire).
What is bromine made of?
The simplest compound of bromine is hydrogen bromide, HBr. It is mainly used in the production of inorganic bromides and alkyl bromides, and as a catalyst for many reactions in organic chemistry. Industrially, it is mainly produced by the reaction of hydrogen gas with bromine gas at 200–400 °C with a platinum catalyst.
Why bromine is called non-metal?
Bromine is a non-metal with seven valence electrons in the outermost shell and has a tendency to gain an electron to complete its octet. Thus, is very reactive in nature and is thus, present in a diatomic form in its elemental state.
What is type of bromine?
Bromine is the third halogen, being a nonmetal in group 17 of the periodic table. Its properties are thus similar to those of fluorine, chlorine, and iodine, and tend to be intermediate between those of the two neighbouring halogens, chlorine, and iodine.
Is Br an alkali metal?
Group 1A (or IA) of the periodic table are the alkali metals: hydrogen (H), lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and francium (Fr). These are (except for hydrogen) soft, shiny, low-melting, highly reactive metals, which tarnish when exposed to air.

What is bromine used for?
Bromine is used in many areas such as agricultural chemicals, dyestuffs, insecticides, pharmaceuticals and chemical intermediates. Some uses are being phased out for environmental reasons, but new uses continue to be found. Bromine compounds can be used as flame retardants.
Why is bromine important to humans?

What is bromine called?
Bromine is a chemical element with the symbol Br and atomic number 35. It is the third-lightest halogen and is a volatile red-brown liquid at room temperature that evaporates readily to form a similarly coloured vapour. Its properties are intermediate between those of chlorine and iodine.

Is bromine an active nonmetal?
The most active group of nonmetals belong to the halogen family. These include fluorine, chlorine, bromine, iodine and . In the periodic table, they appear to the left of the noble gases on the right side of the table. They are so reactive that they are never found in nature by themselves.
