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.
