Atoms And Nuclei Question 2
Question: In the Bohr’s hydrogen atom model, the radius of the stationary orbit is directly proportional to (n = principle quantum number) [MNR 1988; SCRA 1994; CBSE PMT 1996; AIIMS 1999; DCE 2002]
Options:
A) $ \beta $
B) n
C) $ {{n}^{-2}} $
D) $ n^{2} $
Show Answer
Answer:
Correct Answer: D
Solution:
Bohr radius $ r=\frac{{\varepsilon_{0}}n^{2}h^{2}}{\pi Zme^{2}};\ \ \therefore r\propto n^{2} $
