Problem
The success of the Bohr model in explaining atomic spectra relies on two fundamental postulates in addition to classical mechanics. Consider an atom with a single electron bound to a nucleus of charge +Ze.
Answer the following questions qualitatively and concisely. No numerical calculations are required.
(a) State and describe each of the two fundamental postulates that distinguish the Bohr model from a purely classical planetary model of the atom.
(b) Explain how these postulates lead to the appearance of discrete spectral lines rather than a continuous spectrum.
(c) Identify one specific empirical observation or phenomenon that the Bohr model successfully explains and one significant limitation that reveals the model’s inadequacy for more complex atoms.
