What will be the angular momentum in 6th orbit if l is the angular momentum of the electron in the 3rd orbit of hydrogen atom?
Answer & explanation
Correct answer: option 3
The angular momentum of nth orbit is given by
Ln = mvnrn = nh/2π
The angular momentum of third orbit (L3) = 3h/2π = l
The angular momentum of sixth orbit (L6) = 6h/2π = 2(3h/2π)
L6 = 2l
So, the correct option is (c).
