Physics Atomic and Nuclear Physics Balmer Series,Bohr Atomic Structure MCQ (Single Correct)

For the ground state, the electron in the H-atom has an angular momentum = h according to the simple Bohr model. Angular momentum is a vector and hence there will be infinitely many orbits with the vector pointing in all possible directions. In actuality this is not true,

A
Because Bohr model gives incorrect values of angular momentum
B
Because only one of these would have a minimum energy
C
Angular momentum must be in the direction of spin of electron
D
Because electrons go around only in horizontal orbits

Text Solution

Verified by Experts
The correct answer is:
A

Bohr's model give only the magnitude of angular momentum, which is vector
Hence, it does not give the correct value of angular momentum of resolving electron.
