Document Summary

Summary: schrodinger equation results in wave function which enables us to describe the behavior of an electron, in terms of its environment in terms of other electrons, this wave function symbol is directly proportional to the probability of finding electrons in certain regions, wavelengths in one dimension represent parabolic graphs, wave function squared will eliminate negative portion of graph. Quantum numbers: each electron has 4 quantum numbers, wave function corresponding to first 3 quantum numbers is the atomic orbital n: principle quantum number; gives us principle energy levels: n=1,2,3 l: angular momentum quantum number; gives us shape of orbital and denotes sublevels of principle energy levels (n), energy, shape, orientation, l is restricted by value of n, l=n 1, l=0,1,2 (n 1, l=0: s orbital, l=1: p orbital, l=2: d orbital, l=3: f orbital, ml: magnetic quantum number; gives us orientation/spatial distribution of electron cloud, ml is restricted by l, ml = l 0 +l.
