WebMay 12, 2024 · The eletronegativity of atoms is the power of an atom in a molecule to attract other electrons to itself. In a covalent bond, the electronegativity values are the same or very close. If the atoms share an electron equally, the bond is covalent and nonpolar. Most often, an electron is more attracted to one atom than to another.
