Document Summary

The schrodinger equation cannot give exact solutions for any element except hydrogen. # additional features are important in many electron atoms: A limit on the number of electrons in an orbital. A splitting of energy levels into sublevels: the electron-spin quantum number in space of an atomic orbital. The three quantum numbers n, l and m describe the size (energy), shape and orientation. A fourth quantum number describes the spin property, a property of the electron and not. When a beam of atoms that have one or more lone electrons passes through a the orbital nonuniform magnetic field. Each electron behaves as if it were spinning on its axis in one of 2 opposite. The fields are opposite directions so half of the electrons are attracted by the directions, each generating a magnetic field magnetic field and half are repelled by it. Spin quantum number (ms)- can be or - .
