  1. Metallic Bond IB

  2. The Periodic Table of Elements

  3. Periodic Table

  4. Formation of metallic bond • the metal atoms "lose" one or more of their outer electrons • These electrons become delocalized, and free to move throughout the entire metal. • These negative delocalized electrons hold the metal cations together strongly.

  5. Cations packed in “a sea of electrons”

  6. Body Centered Cubic Chromium
