Metallic Bonding

1
Metallic Bonding

• 6.4

2
Metallic Bonding

• The bonding that results from the attraction
  between metal atoms and the surrounding sea of
  e-s.
• For most metals, higher E levels are mt and they
  overlap
• e-s are delocalized in E levels sea

3
Metallic Properties

• High electrical and thermal conductivity.
• Strong absorbers and reflectors of light.
• Malleable hammered into sheets
• Ductile machined into wire

4
Metallic Properties

• Can absorb a wide range of light frequencies
  (orbitals separated by small E diffs)
• When they fall back down, they give off _________
  to the frequency absorbed

5
Metallic Bond Strength

• Enthalpy of vaporization how much E it takes to
  vaporize the metal under constant P
• The higher the enth. Of vap, the stronger the
  bond strength
