What is Electronegativity?

It is a measure of an atom's ability to attract and hold onto electrons. It helps us understand how atoms interact in chemical bonds. Higher electro negativity means an atom attracts electrons more strongly.

Using The Tool

First Element: Select the first element from the dropdown menu.
Second Element: Select the second element from the dropdown menu.
Calculate: Click the "Calculate" button to see the result.
Reset: Click the "Reset" button to clear the selections and start over.

Example Usage

First Element: Oxygen
Second Element: Hydrogen

When you select Oxygen and Hydrogen and click "Calculate," the calculator will show the electronegativity difference.

Formula

The formula to calculate the electronegativity difference is simple:

 $Δ E N = ∣ E N_{1} - E N_{2} ∣$

Variable	Description
$E N_{1}$	Electronegativity of the first element
$E N_{2}$	Electronegativity of the second element
$Δ E N$	Absolute difference in electronegativity

Calculation Examples

Example 1

First Element: Fluorine (F)
Second Element: Lithium (Li)

Calculation:

More Calculators

Electronegativity of Fluorine ( $E N_{F}$ ): 3.98

Electronegativity of Lithium ( $E N_{L} i$ ): 0.98

Difference ( $Δ E N$ ): $∣ 3.98 - 0.98 ∣ = 3.00$

So, the electronegativity difference is 3.00.

Example 2

First Element: Carbon (C)
Second Element: Sulfur (S)

Calculation:

Electronegativity of Carbon ( $E N_{C}$ ): 2.55

Electronegativity of Sulfur ( $E N_{S}$ ): 2.58

Difference ( $Δ E N$ ): $∣ 2.55 - 2.58 ∣ = 0.03$

So, the electronegativity difference is 0.03.
