Halogens

Let us learn about "Halogens"

Halogens are a group of non metallic elements that are placed in Group 17 of the Periodic Table. There are 5 elements that are considered to be a part of this group, and that are widely known as halogens. These elements are Fluorine (F), Chlorine (Cl), Bromine (Br), Iodine (I), and Astatine (At). Being members of the same elemental group, they show a lot of similar halogens properties, but there are some differences as well. The term halogens loosely implies 'salt former', and compounds that contain halogens are commonly referred to as salts

Halogens are the non-metallic in the group 17 of the modern periodic table . Halogens are highly reactive , hence they are present in the form of compound or as ions in nature . Some halogens such as iodine exists as Iodate (IO₃^-) which is the form of ' Oxoanions ' found in sea-water and mineral salts . Even in living organisms there will be the presence of halogens but in the form of halogenated organic compounds.

Halogens exist as the di-atomic molecules naturally . But its existence in nature is less abundant and more in the industries and laboratories . At room temperature and pressure , fluorine and chlorine exist as gases , bromine as liquid and iodine as solid .
