When we stack orbitals we get bands. Bands result in bonding and anti-bonding. Now for Na his s band is half full resulting in the top half to be conductive shell of anti-bonding orbitals.
Take Mg for instance. So his s band is completely full. Why does it conduct ? Because, as I learned, p band partially overlaps with s band thus enabling electrons to jump into conductive band.
Carbon band, after sp3 hybridization(I do not completely understand this principle) makes an energy gap. Why?
Why don't we have this energy gap in metals? Why doesn't this conducting band overlap in insulators too?
