Multiple Choice Options
- A In case of C the valence band is not completely filled at absolute zero temperature.
- B In case of C the conduction band is partly filled even at absolute zero temperature.
- C The four bonding electrons in the case of C lie in the second orbit, whereas in the case of Si they lie in the third.
- D The four bonding electrons in the case of C lie in the third orbit , whereas for Si they lie in the fourth orbit.
Step-by-Step Verified Solution
Electronic configuration of 6 C
6 C = 1s 2 , 2s 2 2p 2
The electronic configuration of 14 Si
14 Si = 1s 2 , 2s 2 2p 6 , 3s 2 3p 2
As they are away from Nucleus, so effect of
nucleus is low for Si even for Sn and Pb are
almost mettalic.
