(a)
Interpretation:
The MO diagram of semiconductor should be drawn.
Concept introduction:
According to band theory, solids are classified as conductors, semiconductors, and insulators.
As per band theory, Bands are continuum of energy levels. The bands are of two types: valence band and conduction band.
Valence band is the band that holds valence electrons and conduction band is the band which is slightly higher in energy than valence band. On the basis of band theory, a partly filled band shows conduction and fully filled band doesn’t show conduction.
(b)
Interpretation:
The MO diagram of insulator should be drawn. The reason for the higher electrical conductivity of semiconductors should be explained.
