Their relative atomic radii to S and the atomic Radius of Phosphorus is 195 and! The term "effective" is used because the shielding effect of negatively charged electrons prevent higher energy electrons from experiencing the full nuclear charge of the nucleus due to the repelling effect of inner layer. When atomic radius is small, the valence electrons are held more tightly to the nucleus resulting in a larger ionization energy. 441451. Table A shows data as evidence for this trend by looking at electron penetration, or the ability of an electron to get close to the nucleus, of selected atoms broken down by their s and p subshells within the same energy level.

Also, the electron or multi-electron takes into account the number of shielding electrons that surrounds the nucleus. Since they are opposite in charge, electrons feel a constant pull towards the protons in the nucleus, while electrons repel each other outside the nucleus. Effective Nuclear Charge Formula . Oxford: Elsevier Ltd., 2005. Also, we solve this to find the effective charge of the electron. "Explicit Periodic Trend of van der Waals Radii." It is called effective because the shielding prevents the outer electrons from experiencing the full charge [1-4]. Follow the steps below to calculate effective nuclear charge by the Slater's rule: Step One : Write down the electronic configuration. International Chemical Safety Card for Chlorine.
