The minimum energy required by a hydrogen atom in ground state to emit radiation in Balmer series is nearly :
Updated On: Jan 13, 2026
- 1.5 eV
- 13.6 eV
- 1.9 eV
- 12.1 eV
Show Solution
The Correct Option is D
Solution and Explanation
The transition from \(n = 1\) to \(n = 3\) for a hydrogen atom produces radiation within the Balmer series:
\[ \Delta E = 12.1 \, \text{eV} \]
Therefore, Option (4) is the correct choice.
