(a) According to the Bohr model, an electron in the ground state of a hydrogen atom orbits the nucleus at a specific radius of 0.53 A°.In the quantum mechanical description of the hydrogen atom, the most probable distance of the electron from the nucleus is 0.53 Å.Why are these two statements different?
(b)Why is the use of Schrödinger's wave equation to describe the location of a particle very different from the description obtained from classical physics?
(c) In the quantum mechanical description of an electron, what is the physical significance of the square of the wave function ψ?
