Question
(a) According to the Bohr model, an electron in the groundstate of a hydrogen atom orbits the nucleus at a specific radius of0.53 angstroms. In the quantum mechanical description of thehydrogen atom, the most probable distance of the electron from thenucleus is 0.53 angstroms. Why are these two statementsdifferent? (b) Why is the use of Schrodinger's wave equation to describethe location of a particle very different from the descriptionobtained from classical physics? (c) In the quantum mechanical description of an electron, whatis the physical significance of the square of the wave function,^2?

A) Quantum mechanical description does not fix the radius ofthe electron. The electron can be located at any point in space,but it is most probable at 0.53 A. B) Electron does not have definite position. It is described by awave, , which is ... C) .... related to the probability density the electron is locatedat a position r, (r)2
