The halogens are the five chemical elements that make up Group 17 on the periodic table: fluorine, chlorine, bromine, iodine, and astatine. The term halogen comes from Greek terms meaning "to produce sea salt." The halogens are all chemically active. For that reason, none occur naturally ...
They are found in group 17 of the Periodic Table, on the extreme right, close to the noble gases. Their valence electron configuration is the reason they are placed in group 17. Why are Group 7 elements called halogens? They are called halogens as they form salts with metals. The term...
