Zeff is determined by the number of electrons surrounding the atom and the charge of the central atom. In a coordination compound, the central atom is surrounded by a number of ligands (electron-donating molecules or ions). The ligands can donate one, two, or three electrons to the central atom. The effective atomic number is the number of electrons that the central atom experiences as if it were in a neutral atom.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"The_Formula_of_Sidgwick_EAN_Rule\"><\/span>The Formula of Sidgwick EAN Rule<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>The Sidgwick EAN Rule states that if an event is both A and not-A, then it is neither A nor not-A.
