When metallic atoms bond, their valence electrons become delocalized. The many electrons form a “sea” of electrons. The attraction between the metal cations and electrons make the metallic bond.

Properties

  • Electrical conductivity
    • Mobile delocalized electrons.
  • Thermal conductivity
    • Closely packed ions allow efficient transfer of heat.
  • Malleable, ductile
    • Non-directional bonding, allows to be manipulated
  • High melting point
    • Large sums of energy to overcome strong electrostatic forces
  • Lustrous
    • Delocalized electrons reflect light

Factors of Strength

  • Number of delocalized electrons
    • Talk about electron cloud density.
  • Charge of cation
    • Higher the stronger
  • Radius of cation
    • Lower the stronger
