MCQ
As electron moves away from the nucleus, its potential energy
- ✓Increases
- BDecreases
- CRemains constant
- DNone of these
✓
Answer
Correct option: A.
Increases
a
An electron moves away from the nucleus, its potential energy increases. The potential energy of the electron is minimum at equilibrium distance from the nucleus. As this distance increases / decreases, its potential energy increases.
An electron moves away from the nucleus, its potential energy increases. The potential energy of the electron is minimum at equilibrium distance from the nucleus. As this distance increases / decreases, its potential energy increases.
Thus, when electron is excited a higher energy orbital it gets farther away from the atom. The further the orbital is from the nucleus, the higher the potential energy of an electron at that energy level.
