WebThe Auger effect or Auger−Meitner effect is a physical phenomenon in which the filling of an inner-shell vacancy of an atom is accompanied by the emission of an electron from the same atom. [1] When a core electron is removed, leaving a vacancy, an electron from a higher energy level may fall into the vacancy, resulting in a release of energy ... Webelectronic configuration, also called electronic structure or electron configuration, the arrangement of electrons in orbitals around an atomic nucleus. The electronic configuration of an atom in the quantum-mechanical model is stated by listing the occupied orbitals, in order of filling, with the number of electrons in each orbital indicated by …

WebThe way we represent shielding is by using the shielding effect formula for Zeff. Zeff (Effective nuclear charge) is the charge an electron "feels" when it is being shielded. The equation for this is: Z e f f = Z − S. Where Z is the number of protons and S is the number of core electrons (or electrons between electron and nucleus).
