MCQ
How many spectral lines are there in the hydrogen spectrum?
- AInfinity
- BZero
- CMultiple
- DOne
✓
Answer
- Multiple
Explanation:
Even though hydrogen has only one electron in its outermost shell, it has multiple spectral lines.
This is because hydrogen has many energy levels.
When the electron excites from a lower level of energy into a higher level, then it releases a photon, and this photon is the one that appears as spectral lines.
