Table of Contents Elements and Their Properties Section 1 • Metals

Because an atom of a halogen has seven electrons in its outer energy level, only one electron is needed to complete this energy level. If a halogen gains an electron from a metal, an ionic compound, called a salt is formed. The Halogens In the gaseous state, the halogens form reactive diatomic covalent molecules and can be identified by their distinctive colors. Chlorine is/
