Statement I Band gap in germanium is small.
Statement II The energy spread of each germanium atomic energy level is infinitesimally small.
Statement II The energy spread of each germanium atomic energy level is infinitesimally small.
Solution:
Germanium, semi-conductor substance, has small band gap in comparison to insulator (non-metal).
On moving top to bottom in the group 14 band gap decreases.
