Halogen
A nonmetal in Group 17 of the periodic table; highly reactive and forms salts with metals.
Diatomic molecules
Halogens typically exist as diatomic molecules (F2, Cl2, Br2, I2) under standard conditions.
Reactivity trend in halogens
Reactivity decreases down the group from fluorine to iodine.
Alkali halides
Salts formed when halogens react with alkali metals (e.g., NaCl, KBr).
Common oxidation state
Most common oxidation state of halogens is -1; higher oxidation states occur in interhalogen compounds and oxo-halogens.
Physical state and color at room temperature
F2 and Cl2 are gases, Br2 is a liquid, I2 is a solid; colors: F2 (pale yellow), Cl2 (greenish-yellow), Br2 (reddish-brown), I2 (violet).
