How to use the bond polarity calculator
Classify a bond from the electronegativity difference. Enter electronegativity 1, electronegativity 2 in the fields above; the difference, bond type are computed instantly and plotted on the chart so you can see how the answer changes.
Formula
Variables
- e1 — Electronegativity 1
- e2 — Electronegativity 2
Worked example
With electronegativity 1 = 3.16, electronegativity 2 = 0.93, the calculator gives difference ≈ 2.23; bond type ≈ Ionic.
Frequently asked questions
What is the formula for the bond polarity calculation?
Difference = abs(e1-e2). Bond type = [Difference]>1.7?"Ionic":([Difference]>0.4?"Polar covalent":"Nonpolar covalent"). Here e1 is electronegativity 1, e2 is electronegativity 2.
What inputs do I need for the bond polarity (electronegativity difference) calculator?
You need electronegativity 1, electronegativity 2. Each field is pre-filled with a typical example so you can see how the result responds as you edit the numbers.
How do I use this calculator?
Type values into the input fields. Results and the chart update instantly. Use Reset to restore the example values, Copy results to paste them elsewhere, or Share to copy a link that preserves your inputs.
Is the result exact?
Calculations use standard formulas and double-precision arithmetic, then display about seven significant figures. Real-world measurements carry uncertainty, so treat results as estimates unless your inputs are exact.
