The energy of the photon emitted when an electron jumps from n = 5 to n = 2 in a hydrogen atom is?
Q1. The energy of the photon emitted when an electron jumps from n = 5 to n = 2 in a hydrogen atom is?
Answer: 2.86 eV
Explanation: Using energy level formula, the energy difference between n = 5 and n = 2 is 2.86 eV; option B is for n = 4 to n = 2.
