Metals have high melting points and high boiling points as they have strong metallic bonds. Electrical resistivity, represented by the greek letter ρ (rho), is a measure of how strongly a material opposes the flow of electric current. Its thermal conductivity (2,200 w/m•k) is five times greater than the most conductive metal (ag at 429); Semiconductors have conductivities between 10.

I will give a brief account (and a good reference) below. Some common properties of metals include: The number of conduction electrons is constant, depending on neither temperature nor impurities. They generally have fewer valence electrons than valence orbitals, so that empty orbitals in the valence shell exist. In metallic aluminum the three valence electrons per atom become conduction electrons.
