Cannot project on zero atomic wavefunctions
Did you know?
WebNot all wavefunctions have nodes, the lowest energy one does not, (e.g. the S orbital in atoms, zero point vibration and zero rotation in molecules, lowest MO in a molecule). The larger the number of nodes a wavefunction has the greater the energy eigenvalue. Some pictures of wavefunctions and nodes has been given in the answer by @Brian. WebTo solve this problem, we assume that the potential between two electrons is negligible and separate the initial equation into two equations, for each representing the electron interaction with the nucleus, as follows: for Solving these equations, we obtain the following formulas of the wavefunctions, expressing in spherical coordinates:

That is, the Bohr picture of an electron orbiting the nucleus at radius corresponds to the most probable radius.
