Vedclass · Answer

(B) According to the Bohr model,the total energy of an electron in the $n^{	ext{th}}$ energy level of a hydrogen atom is given by $E_n = -\frac{13.6}{n^2} 	ext{ eV}$.If the energies $E_n$ are different,the principal quantum numbers $n$ must be different.The orbital angular momentum of an electron in the $n^{	ext{th}}$ orbit is given by $L_n = \frac{nh}{2\pi}$.Since the angular momentum $L_n$ is directly proportional to $n$,if the values of $n$ are different,the values of the angular momentum $L_n$ must also be different.Therefore,it is not possible for the electrons to have different energies but the same orbital angular momentum.

Consider two different hydrogen atoms. The electron in each atom is in an excited state. Is it possible for the electrons to have different energies but the same orbital angular momentum according to the Bohr model?
