Problem
A plot of radial distance (r) versus probability of finding the electron in the ground state of hydrogen shows a maximum at r=a0 but a non-zero value for other r as well. What does this observation imply about the adequacy of the Bohr model?
(a) The Bohr model is adequate because it predicts exactly the same probability distribution for the ground state.
(b) The Bohr model is adequate because it incorporates quantised angular momentum, which already explains the observed data.
(c) The Bohr model is inadequate because it confines the electron strictly to r=a0, predicting zero probability elsewhere.
(d) The Bohr model is adequate because the small probability at other r can be attributed to thermal vibrations of the nucleus rather than any flaw in the model.
