Web7 dec. 2024 · The effective nuclear charge (Zeff) can be formulated as: with Z = nuclear charge = atomic number S = shield constant Shielding constants are constants that are generated from the core attraction of electrons in the inner shell Rules for calculating shield constants-S (Slater’s Rules) 1. Electrons in orbitals are grouped according to the shell WebEffective nuclear charge, Z eff is the pull exerted on a specific electron by the nucleus, taking into account any electron–electron repulsions. For most atoms, the inner electrons partially shield/block the outer electrons from the pull of the nucleus, and thus:. Z eff = Z−shielding (blocking positive charge by other electrons). Shielding is determined by the …
