Calculate Zeff as atomic number Z minus the shielding constant s.
| Zeff | – |
Use this calculator for Slater’s-rules homework when you have Z and s and need Zeff for a valence electron.
Zeff = Z − s. This tool does not compute s for you; type the shielding number from your table or Slater count. Zeff is dimensionless in the usual Slater treatment.
Atomic number Z: Atomic number of the element, 17 for chlorine.
Shielding constant s: Shielding constant from Slater or a table, dimensionless, for example 10.9.
Zeff: Effective nuclear charge felt by the electron.
