One of the Main Problems with the Bohr Model of the Hydrogen

Multiple Choice

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 = E_i − E_f.
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 E_n = −13.6 eV.
