Effective Nuclear Charge Calculator
Calculate the effective nuclear charge experienced by electrons using Slater's rules.
Valence Electron (3s)
Nuclear Charge (Z)
11
Shielding (Ο)
8.80
Zeff
2.20
Zeff = Z - Ο = 11 - 8.80 = 2.20
Zeff by Orbital
| Orbital | Electrons | Shielding (Ο) | Zeff |
|---|---|---|---|
| 1s | 2 | 0.30 | 10.70 |
| 2s | 2 | 2.05 | 8.95 |
| 2p | 6 | 3.45 | 7.55 |
| 3s | 1 | 8.80 | 2.20 |
Slater's Rules Summary
- Same group (ns, np): 0.35 each (0.30 for 1s)
- (n-1) shell s,p electrons: 0.85 each
- Lower shell electrons: 1.00 each
- d and f electrons: 1.00 for s,p valence
