... • For polyelectronic (i.e. real) atoms, a direct solution of the Schrodinger Equation is not possible. (Can’t solve the 3 body motion problem; Z12.61) • When we construct polyelectronic atoms, we use the hydrogen-atom orbital nomenclature to discuss in which orbitals the electrons reside. • This is ...

Part 3: Quantum numbers and orbitals
... With this basic knowledge of quantum numbers and orbitals, we can now begin to develop a picture of the atom and to write electron configurations; this is a very important skill in chemistry. Based on the electron configuration of each element, we can explain and predict the behavior of that elemen ...
