NEET Physics Bohr Model MCQ Question

Type: MCQ-conceptual-Medium-Class 11

Taking the Bohr radius as a₀ = 53 pm, the radius of Li⁺⁺ ion in its ground state, on the basis of Bohr’s model, will be about

A

53 pm

B

27 pm

C

18 pm

D

13 pm

Correct Answer

Option D

Detailed Explanation

In the Bohr model, the radius of an ion is proportional to n²/Z. For Li⁺⁺, Z = 3 and n = 1, so the radius is smaller than that of hydrogen, which is 53 pm.
