CHEMITRY CALCULATOR
Effective Charge
A precise tool.
What is the Effective Charge & How does it work?
The effective charge of an atom is the net positive charge experienced by an external electron due to the shielding effect of inner electrons.The shielding constant (S) depends on the number of inner electrons and their distance from the outer electron. It is typically estimated using Slater’s rules.
Z_{text{eff}} = Z – S
Z_eff = Effective Charge, Z = Atomic Number, S = Shielding Constant
