Question
What is likely to be orbit number for a circular orbit of diameter 20 nm of the hydrogen atom if we assume Bohr orbit to be the same as that represented by the principal quantum number ?
Options
A.10
B.14
C.12
D.16
Solution
Radius = 0.529 
(Ao) = 10 × 10-9 m
So, n2 = 189 or, n ≈ 14
(Ao) = 10 × 10-9 mSo, n2 = 189 or, n ≈ 14
