    Q:

    		 The valence band of an atom is the highest range of electron energies in which electrons are normally present. The conduction band is the range of energies where electrons are free enough to move delocalized from atom to atom. However, not all elements have electrons that lie within their conduction bands. Which of the following elements would be expected to have its valence band and its conduction bands overlapping?
