Atomic Structure Question 405

Question: According to Bohr’s theory, the angular momentum of an electron in 5th orbit is

Options:

A) $ 10h/\pi $

B) $ 2.5h/\pi $

C) $ 25h/\pi $

D) $ 1.0h/\pi $

Show Answer

Answer:

Correct Answer: B

Solution:

  • Angular momentum of en electron in $ n^{th} $ orbit is given by $ mvr=\frac{nh}{2\pi } $ For n= 5, we have Angular momentum of electron $ =\frac{5h}{2\pi }=\frac{2.5h}{\pi } $
