But yeh to distinction h naa on the basis of band theory i want to understand the band theory in which vo interatomic spacing n crystal lattice spacing is there.

Seeeeeeeeeeeee In some solids the conduction band and valence band are overlapped. So energy band gap is 0. Due to this electron can move freely in conduction band. Hence conduction occur. And these solids are called CONDUCTOR or METALS. In some solids the energy band gap is more than 3eV due to which no electron can exicte thermally in the conduction band. Hence no conduction takes place. And the solids which have this property are called INSULATORS. In some solids the energy band gap between conduction band and valence band is less than 1eV. Due to this small amount of electron can thermally excite to the conduction band and can move freely. These solids have intermediate of CONDUCTOR and INSULATOR. And the solids which have this kind of property are called SEMICONDUCTORS. HOPE YOU UNDERSTAND!!!
