WebThe Shielding Constant given Effective Nuclear Charge formula is defined as the summation of the contribution of each electron in screening from the force of the nucleus according to Slater's Rule and is represented as σ = z-Z* or Shielding Constant in NMR = Atomic Number-Effective Nuclear Charge. WebSlater's rules provide a method to estimate the effective nuclear charge and shielding constant for valence electrons in multi-electron atoms based on the electron configuration of the atom. The rules are as follows: 1. Electrons in the same group (vertical column of the periodic table) are assumed to shield each other equally.

WebDec 4, 2016 · As a specific case, let's compare the shielding experienced by a 2p electron in carbon versus neon. The carbon electron configuration is $1s^22s^22p^2$. Using Slater's rules, we can calculate that the shielding coefficient for a 2p electron is 2(0.85) + 3(0.35) = 2.75. So the effective nuclear charge experienced by the 2p electron is 6-2.75=3.25.
