For 10 points, name these eponymous rules used to estimate the effective nuclear charge experienced by electrons.
A self-consistent field method to obtain the values predicted by these was developed by Clementi and Raimondi. These statements extended a system developed for by Clarence Zener for second period elements, and they ignored the radial nodes of the wavefunction since the nodes occur much closer to the nucleus compared to the hydrogen atom. The last one of these statements assigns a (*) modified value to the principle quantum number, and that quantity divides the main quantity calculated using these rules. They ignore electrons in outer shells compared to the electron being considered, and they group ns and np orbitals together. In addition, they assign certain d and f electrons a value of one due to their poor penetrating power.
