📐Step-by-Step Mathematical Derivation

Given ➔ Formula ➔ Solve
1. Given Quantities:
Atom 1: Hydrogen (H) — Electronegativity = 2.2
Atom 2: Chlorine (Cl) — Electronegativity = 3.16
2. Governing Formula:
ΔEN = |EN₁ - EN₂|
3. Substitute Values:
ΔEN = |2.2 - 3.16|
4. Calculated Result:
ΔEN = 0.96 (POLAR COVALENT)
5. Chemical Interpretation:Electrons are pulled closer to Cl (creating δ− partial negative charge) and away from H (creating δ+).

Electronegativity Scale Conventions

Nonpolar Covalent: ΔEN < 0.4 (equal sharing).

Polar Covalent: 0.4 ≤ ΔEN < 1.7 (unequal sharing, permanent dipole).

Ionic Character: ΔEN ≥ 1.7 (electron completely transferred).
