Each atomic valence level is delocalized over the entire lattice and broadened out into a band, which is incompletely filled with electrons. Hence high mobility of electrons and ability to conduct electricity and heat.
Bonding is not strongly dependent on direction (contrast covalent) so metals often quite densely packed, and layers can be slid past each other while still bonding - malleability, ductility.
Some, not all, form very stable lattices, contrast tungsten with sodium and mercury.

Metals involve the electrostatic attraction between metal cations and the sea of delocalised valence elctrons. Metals often exhibit such properties as:
-High electrical/thermal conductivities
-Dense
-High melting point/boiling point
-Malleable/ductile
