PRACTICE / Hydrogen energy levels
Which energy belongs to the emitted photon?
In the simple hydrogen energy-level model, Eₙ = −13.6/n² eV. An atom makes a transition from n = 3 to n = 2.
What energy does the emitted photon have?
Organize the givens & assumptions
- Initial level: n = 3
- Final level: n = 2
- Ground-state coefficient: 13.6 eV
Neglect recoil, fine structure and external fields. Use the stated bound-state energy model.
- A
- B
- C
- D
