Question

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

Answer 1

Answer: (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.
