Group 17 elements 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.These highly reactive non-metals are called “halogens” because they give salts when they react with metals. These elements have one electron short for octet configuration. Therefore, these elements sharing 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.
