For 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 reality this is not true,
- because Bohr model gives incorrect values of angular momentum
- because only one of these would have a minimum energy
- angular momentum must be in the direction of spin of electron
- because electrons go around only in horizontal orbits
Answer
(B) because only one of these would have a minimum energy
