METALS
Metallic bonding - metal + metal
Electron sea model
- delocalized "sea" of mobile valence electrons around a regular
but non-rigid array of metal ions (nuclei + core electrons)
Metal Properties:
• Solids
(liquids)
• malleable
(beaten), ductile (extruded)
• good electrical
and thermal conductors
• moderate melting
pt, and moderately
high boiling points
high boiling points
