InterviewSolution

1.	Stonsium (Sn) and silicon (Si) both belong to group IV elements but Sn is a metal whereas Si is a semiconductor. Why?
Answer» Sn is a metal because the energy gap in its energy band diagram is zero, whereas Si is a semiconductor because the energy gap in its band diagram is 1.1 eV.
