Question

If Hydrogen electron is excited to an orbit of energy -0.85 eV in an atom then maximum possible number of transitions to lowest energy levels is

(1) 6

(2) 3

(3) 5

(4) 2

Answer 1

Correct option is (2) 3

\(- \frac{13.6z^2}{n^2} = -0.85\)

⇒ n = 4

For max Transitions:

4 → 3 → 2 → 1

3 transitions
