Answer: The correct option is 1.
Explanation: Energy associated to the ground state energy level for H-atom:
Energy associated to the for H-atom = (Z for H-atom = 1)
Energy difference is calculated by:
- For option 1:
- For option 2:
- For option 3:
- For option 4:
From the above calculations, it is seen that the largest amount of energy will be required for the the transition from n= 1 to n = 2.
Hence, the correct option is 1.
