The diagram shows different transitions across the energy levels for an electron in a certain atom. Among these, which transition represents the emission of a photon with the most energy?

- A (II)
- B (I)
- C (IV)
- D (III)
Answer & Solution
Correct Answer
(D) (III)
Step-by-step Solution
Detailed explanation
Since, energy, \(E=13.6 Z^2\left(\frac{1}{n_f^2}-\frac{1}{n_i^2}\right)\) where, \(Z\) is atomic number and \(n\) is orbital number. From given diagram,…
