Type: MCQ-numerical-Easy-Class 12
The radius of inner most orbit of hydrogen atom is 5.3×10⁻¹¹ m. What is the radius of third allowed orbit of hydrogen atom?
A
1.06 Å
B
1.59 Å
C
4.77 Å
D
0.53 Å
Correct Answer
Option C
Detailed Explanation
The radius of the nth orbit is given by r_n = n^2 * r_1. For n = 3, r_3 = 9 * 5.3×10^−11 m = 4.77 Å.
