Chemical Bond Polarity Calculator
Chemical Bond Polarity Calculator helps determine whether a covalent bond between two atoms is polar or non-polar. It uses the difference in electronegativity values to identify the type of bond formed. This tool is useful for chemistry students and professionals to understand electron sharing behavior in molecules and the tendency of atoms to attract electrons.

Electronegativity Difference Formula
Where:
- $$EN_1$$ and $$EN_2$$ are the electronegativities of the two atoms
- $$\Delta EN$$ is the absolute difference, which determines the bond type:
- $$\Delta EN < 0.4$$: Non-polar covalent bond
- $$0.4 \leq \Delta EN \leq 1.7$$: Polar covalent bond
- $$\Delta EN > 1.7$$: Ionic bond (not covalent, shown for reference)
Bond polarity describes the distribution of electron density in a chemical bond. This calculator is especially useful in identifying the type of bond formed in a diatomic molecule. Users can select two chemical elements, and the calculator fetches their standard electronegativity values to calculate the difference. The result explains if the bond is polar or non-polar, helping in molecular geometry and reactivity predictions. This is crucial in fields like organic chemistry, pharmacology, and material science.
I hate this I was forced to use this during science class.
If there’s more than 2 elements how to determine the electronegativity???
This isn’t helpful at all. I need to find differences between three elements not two! (CHCI3)
u are literally 0 iq in chemistry
CHCI3 is a polar element get some help
Nano material
This is terrible.
Every calculation of the dozen I made is polar covalent.
Must be a bug.
The calculations are correct, but not the “Type of Bond”
Polar covalent bonds are if the END are more than 0.4, and nonpolar is 0.4 or less. The “formula” on this website is wrong.
This is very helpful for a chemistry student.
My teacher marked this wrong. It doesn’t work. I did it ten times, and I got the same answer. Please upvote this if you agree.
These tend to be more accurate:
0.4 but 1.7 = ionic
Also look at the periodic table. As the elements progress from left to right, the electronegativity increases. As the elements progress down the row from top to bottom, the electronegativity decreases. The larger the difference between the electronegativity of the two elements, the more polar it is.
Hope it helps! 🙂
Sorry: here are the measurements:
if the difference is less than 0.04, the bond is non-polar covalent
If the difference is greater than 0.04 but less than 1.7, the bond is polar covalent
If the difference is greater than 1.7, the bond is ionic
Your ‘difference’ list is very useful, thank you, but I think you added an extra decimal place. Shouldn’t it be:
If the difference is less than 0.4 (not 0.04)…. Actually, the number I was given was 0.5 (rounded up, I guess).
As to whether the calculator doesn’t work – could you give an example (it works as far as I can see)?
