Document Summary

Schrodinger equation does not give exact solutions for the energy levels of many electron atoms. But unlike bohr, it gives great approximate answers. Important notes; 4th quantum number, limit on the number of electrons in an orbital, splitting of energy levels into sublevels. N l ml describe the size (energy), shape and orientation of an atomic orbital. > property of the electron and not the orbital. Each electron behaves like a spinning charge and generates a tiny magnetic field which can have one of two spin. > two electron fields have opposing direction: in experiments: electrons are attracted by external magnetic field while other haf are repelled by it. Each electron in an atom is described completely by a set of four quantum numbers. > first e- in he ground state has the same set of quantum numbers as the electron in. Exclusion principle; no two electrons in the same atom can have the same four quantum numbers.
