About Electronegativity

Electronegativity is a measure of an atom's ability to attract shared electrons in a chemical bond. The electronegativity difference between two atoms helps predict the type of bond that will form between them.

Electronegativity Formula

The electronegativity difference (ΔEN) is calculated using:

ΔEN = |EN₁ - EN₂|

Where EN₁ and EN₂ are the electronegativity values of the two elements.

Bond Type Interpretation

• 0.0 - 0.4: Nonpolar covalent bond
• 0.4 - 1.7: Polar covalent bond
• Above 1.7: Ionic bond
