How do you calculate the effective nuclear charge of carbon?

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 … Web24 mei 2013 · How can I calculate the effective atomic number (Zeff.) for the silver-water mixture if the concentration of silver was 10 mg/M for example?
