Atomic Structure Question 51

Question: According to Bohr-s principle, the relation between principle quantum number $ (n) $ and radius of orbit is

Options:

A) $ r\propto n $

B) $ r\propto n^{2} $

C) $ r\propto \frac{1}{n} $

D) $ r\propto \frac{1}{n^{2}} $

Show Answer

Answer:

Correct Answer: B

Solution:

Bohr suggest a formulae to calculate the radius and energy of each orbit and gave the following formulae $ r_{n}=\frac{n^{2}h^{2}}{4{{\pi }^{2}}kme^{4}Z} $ Where except $ n^{2} $ , all other unit are constant so $ r_{n}\propto n^{2} $ .
