What is Electronegativity?

The propensity of an atom in a molecule that attracts the shared pair of electrons towards itself is called electronegativity. Electronegativity measures on different scales. The most common scale that is used was designed by Linus Pauling.

We will look into the formula of Electronegativity is,

Electronegativity Difference = |χ of first element - χ of second element|


χ is the electronegativity

|x|  is Absolute value of  x

How to Calculate Electronegativity?

To calculate the electronegativity you can follow the steps that are given below. Go through the guidelines carefully.

  • Initially, note down the values that are given in the problem.
  • Then look into the periodic table that includes it and read it for the selected element.
  • Then, apply the electronegativity formula, i.e., ED = |χ of the first element - χ of the second element| and subtract the two elements.
  • Then, determine the type of chemical bond that the selected elements may form.
    • If the electronegativity is less than 2.00 then the bond is ionic.
    • If the electronegativity is less than 0.4 then the bond is Covalent.
    • If the electronegativity is between 0.4 and 2.00 then the bond is polar covalent.
  • Next, simplify the problem by substituting the values. And check the answer with the above three conditions to identify the bond.
  • Finally, get the answer easily.

FAQs on Electronegativity Calculator

1. Define Electronegativity?

Electronegativity is the atom that has the ability to attract electrons in the pair. And mostly used one is the Linus Pauling scale.

2. How to use the Electronegativity Calculator?

To use the electronegativity calculator, simply give the two elements, and then by clicking on the calculate button, gives you the result instantly.

3. How to find Electronegativity?

Electronegativity can be calculated by subtracting smaller electronegativity from the larger one. i.e., Electronegativity Difference = |χ of first element - χ of second element|.

4. What is the electronegativity of CH4?

CH4 is a nonpolar molecule that has carbon and hydrogen bonds. The values of carbon and hydrogen from the periodic table are 2.55 and 2.2 which results in almost zero partial charges.

5. Is 1.7 polar or ionic?

If you get the electronegativity difference of 1.7 as per our conditions if you get the electronegativity difference between 0.5 and 1.7 then it is polar covalent.
