Thermal and electrical conductivity. Why are metals good conductors of heat and electricity? Electric current is the flow of electrons in a wire. ... They are no longer firmly held by a specific atom, but instead they can move freely through the lattice of positive metal ions.

Metal particles are held by strong metallic bounds that is they have high melting and boiling points. Thus free electrons in metals can move through the metals allowing electricity to pass through the metals.
