Electron Sea Model

• Proposes that all the metal atoms in a metallic solid contribute their valence electrons to form a sea of electrons

Delocalized Electrons

• electrons present in the outer energy levels of the bonding metallic atoms that are not held by any specific atom and can move easily from one atom to the next

Metallic Bond

• The attraction of a metallic cation for celocalized electrons
