Atomic Structure Question 50
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 $ .
