Chemistry-Bohr's Model
NEET Chemistry Bohr's Model MCQ Question
Type: MCQ-diagram based-Hard-Class 11
Consider a diagram depicting a hydrogen atom according to Bohr's model. The diagram shows an electron moving in a circular orbit around a nucleus. Which of the following correctly describes the radius of the n=3 orbit for this atom?
A
The radius is proportional to n².
B
The radius is proportional to n.
C
The radius is inversely proportional to n².
D
The radius is inversely proportional to n.
Correct Answer
Option A
Detailed Explanation
According to Bohr's model, the radius of an electron's orbit in a hydrogen atom is proportional to the square of the principal quantum number, n². This follows from the formula r = 0.0529 n²/Z for hydrogen-like atoms.
