and both have same lattice structure, having 4 bonding electrons in each. However, is insulator where as Si is intrinsic semiconductor. This is because
View answer and explanation
Correct option: C
The four bonding electrons in the case of lie in the second orbit, whereas in the case of they lie in the third
The difference in conductivity between C and Si is due to the energy band gap, which is influenced by the orbital location of bonding electrons. Carbon's electrons are closer to the nucleus, resulting in a larger energy gap.
