Electronegativity vs. Polarity: What's the Difference?

Edited by Sawaira Riaz || By Sara Rehman || Published on December 2, 2023
Electronegativity is an atom's ability to attract electrons, while polarity refers to the distribution of electric charge across a molecule.

Key Differences

Electronegativity is a chemical property that describes how strongly an atom can attract or hold onto electrons. In contrast, polarity is a broader concept that refers to the distribution of electric charges in a molecule, determined by the arrangement of atoms and the electronegativity of each atom.

While electronegativity is specific to individual atoms, polarity is a property of molecules. Electronegativity influences polarity, as differences in electronegativity between atoms in a molecule can lead to unequal sharing of electrons, creating polar molecules.

Electronegativity is quantified on various scales, such as the Pauling scale, and is specific to each element. Polarity, however, is not quantified in the same way; it is a qualitative description of a molecule’s charge distribution, influenced by the relative electronegativities of its constituent atoms.

In the context of chemical bonding, electronegativity helps predict bond types (ionic, covalent, or polar covalent), whereas polarity is essential in determining a molecule's physical properties, like solubility and boiling point.

Electronegativity is a concept used primarily in atomic and molecular chemistry. Polarity, however, has a wider application, extending to fields like physical chemistry and materials science, where it explains molecular interactions and behaviors.
