Question

In a certain electronic transition in the hydrogen atoms from an initial state (1) to a final state (2), the difference in the orbital radius (r1 - r2) is 24 times the first Bohr radius. Identify the transition.

Options

A.5 → 1
B.25 → 1
C.8 → 3
D.6 → 5

Solution

r1 - r2 = 24 × (r1)H
= 24 × 0.529
∴   (n12 - n22) = 24
So,    n1 = 5    and     n2 = 1
