Calculate Percent Ionic Character
About Percent Ionic Character
Percent ionic character describes the degree to which a chemical bond is ionic rather than covalent. It's expressed as a percentage from 0% (pure covalent) to 100% (pure ionic).
Pauling's Method:
% Ionic = 100 × (1 - e^(-0.25 × (χ_A - χ_B)²))
Hannay-Smith Method:
% Ionic = 100 × (IE - EA) / (IE + EA)
From Dipole Moment:
% Ionic = 100 × (μ_observed / μ_ionic)
Where:
- χ_A, χ_B = Electronegativities of elements A and B
- IE = Ionization energy
- EA = Electron affinity
- μ = Dipole moment
Percent ionic character helps predict bond properties, molecular behavior, and chemical reactivity.
