Effective Charge Formulas
Effective Nuclear Charge
Zeff = Z - σ
- • Zeff = Effective nuclear charge
- • Z = Atomic number
- • σ = Shielding constant
- • Higher Zeff = stronger attraction
Slater's Rules
- • Electrons in same shell: 0.35
- • Electrons in n-1 shell: 0.85
- • Electrons in n-2 and lower: 1.00
- • 1s electrons: 0.30
- • Used to calculate shielding
