Chemistry-Bohr's Model
NEET Chemistry Bohr's Model MCQ Question
Type: MCQ-numerical-Medium-Class 11
Calculate the radius of the first Bohr orbit for a hydrogen-like ion with atomic number Z = 3.
A
0.0529 nm
B
0.0158 nm
C
0.00176 nm
D
0.0529 m
Correct Answer
Option B
Detailed Explanation
The radius of the orbit in a hydrogen-like ion is given by r = 0.0529 nm * n^2 / Z. For n=1 and Z=3, r = 0.0529 nm / 3 = 0.0158 nm.
