Question
Each orbit is associated with a definite energy, they are also called as _________.
- Valence shell
- Energy states
- Energy levels
- Both B and C
Hint:
Each orbit of an atom is associated with definite energy, and they are also called energy levels.
The correct answer is: Both B and C
- Each orbit of an atom represents the energy levels of electrons in it.
- According to the increase in shell number, the energy level decreases.
- Hence the shells or orbits are also called energy levels.
