Statement I Band gap in germanium is small.
Statement II The energy spread of each germanium atomic energy level is infinitesimally small.
Options
- AStatement I is true, Statement II is true, Statement II is a correct explanation for Statement I
- BStatement I is true, Statement II is true, Statement II is not a correct explanation for Statement I
- CStatement-I is true, Statement II is false
- DStatement-I is talse, Statement II is true
Correct answer
C. Statement-I is true, Statement II is false
Step-by-step 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.
