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.
