Group 17 Elements

What are Group 17 Elements Called?

Group 17 elements also called Halogens in the periodic table contain the chemical element fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At) with ns2 np5 valence shell electronic configuration.

Group 17 elements in the periodic table

The name halogens is obtained from the Greek word halo means salt and genes mean producing. Therefore, these seven highly reactive non-metals are called “halogens” because they give salts when they react with metals.

These chemical elements are one electron short of octet configuration or the nearest noble gas electronic configuration. Therefore, these elements share one electron to form a covalent bond or gain one electron and form an ionic bonding. The detailed properties, use, and compounds of Group-17 elements or halogens are given below the individual topics in learning chemistry.
