Effective Nuclear Charge Calculator
Calculate the effective nuclear charge ($Z_{\text{eff}}$) of an electron
Formula: $Z_{\text{eff}} = Z - S$
Where $Z$ is the atomic number (total protons) and $S$ is the shielding (or screening) constant determined by inner-shell electrons.
Where $Z$ is the atomic number (total protons) and $S$ is the shielding (or screening) constant determined by inner-shell electrons.

Calculation Results
⚠️ The shielding constant ($S$) is typically estimated using Slater's rules, which provide an approximation of electron-electron repulsion. Exact effective nuclear charge values in multi-electron systems require advanced quantum mechanical calculations.
