One of the main problems with the Bohr model of the hydrogen atom when compared with the results of the methods of quantum mechanics used to describe atoms, was that the Bohr model predicted:
A)the ground state angular momentum was L = 1
B)the frequency of the radiation emitted when an electron 'jumps' from one allowed orbit to another was hf = Ei - Ef.
C)the potential energy function for the hydrogen atom was given by V(r) = -ke2/r.
D)the energy of the ground state of the hydrogen atom was En =-13.6 eV.

The Bohr model predicted that the ground state angular momentum of the electron in a hydrogen atom was L = 0, whereas quantum mechanics predicts that the ground state has an angular momentum of L = 0 as well. Therefore, the Bohr model did not have a problem with predicting the ground state angular momentum of the electron. However, it did have problems with accurately predicting other aspects of the hydrogen atom's behavior, such as the exact frequencies of the emitted radiation and the potential energy function.
