Question: In Bohr-s model, atomic radius of the first orbit is $ \gamma $ , the radius of the 3rd orbit, is

Options:

A) $ \gamma /3 $

B) $ \gamma $

C) $ 3\gamma $

D) $ 9\gamma $

Show Answer

Answer:

Correct Answer: D

Solution:

$ r\propto n^{2} $ For Ist orbit $ \gamma =1 $ For IIIrd orbit = $ \gamma \propto 3^{2}=9 $ So it will 9 $ \gamma $ .
