Metallic Bonding

• Metallic Bonding

  • Metal + metal
  • Strongest bond of the 3
  • Sea of delocalized electrons
• Properties of Metals

  • Shiny
  • Malleable (become any shape) & ductile (thin to wires)
  • Usually high melting & boiling point
  • Conducts heat & electricity
  • Solids at room temperature (except: mercury)
• Structure of Solids (metals)

  • Lattice form
  • Particles close together
  • Surrounded by sea of delocalized electrons - e- jumps around & moves randomly
  • Very strong attraction - e- constantly holding on to positive ion
  • More delocalized = stronger attraction
  • Nucleus becomes +ve charge
• Groups & Melting Points

  • 1st period = highest melting point
  • cuz electron is closer to protons
  • More electrons = higher melting point
  • Melting points increase across a period
• Metallic: Conducting Electricity


  • Metals can conduct electricy cuz of the movement of delocalized electrons
  • More delocalized electrons = better electricity conductor
