Metallic Bonding • Chemical bonding is different in metals than it is in ionic, molecular, or covalent-network compounds. • The unique characteristics of metallic bonding gives metals their characteristic properties: • electrical conductivity

• ductility (ability to be drawn, pulled, or extruded through a small opening to produce a wire) • shiny appearance

The Metallic Bond Model • In metals, the metal atoms lose their outer electrons to form metal cations. • In a metal, the vacant orbitals in the atoms’ outer energy levels overlap. • This overlapping of orbitals allows the outer electrons of the atoms to roam freely throughout the entire metal.

• These electrons are delocalized, - which means they do not belong to any one atom but move freely about the metal’s network of empty atomic orbitals. • Delocalized – “not fixed in place” or “free to move”.

• These mobile electrons from a sea of electrons around the metal atoms, which are packed together in a crystal lattice.

METALLIC BOND The chemical bonding that results from the attraction between metal atoms and the surrounding sea of electrons is called metallic bonding.
