How It Works: Formula & Explanation
The percent ionic character of a chemical bond is calculated using the electronegativity difference between the two bonded atoms.
Formula Used:
% Ionic Character = [1 - e^(-0.25 × (ΔEN)²)] × 100
Where ΔEN is the absolute difference in electronegativity between the two atoms:
ΔEN = |ENA - ENB|
Bond Type Classification:
- Nonpolar Covalent: ΔEN < 0.5
- Polar Covalent: 0.5 ≤ ΔEN ≤ 1.7
- Ionic: ΔEN > 1.7
This calculation is based on Pauling's electronegativity scale and provides an estimate of the ionic character in a chemical bond.
