What is a direct result of increased electronegativity in atoms?

Increased electronegativity in atoms primarily leads to greater ability of an atom to attract electrons in a chemical bond. This increased attraction strengthens the interaction between atoms, resulting in a higher likelihood of forming ionic bonds. When an atom with high electronegativity bonds with an atom of much lower electronegativity, such as sodium and chlorine, the stronger pull of the more electronegative atom (chlorine, in this case) allows for the complete transfer of an electron, leading to ionic bond formation.

Ionic bonds are characterized by the electrostatic attraction between positively and negatively charged ions, which occurs because one atom has a much stronger tendency to attract electrons than the other. This propensity for forming ionic bonds is a direct consequence of the differences in electronegativity between the bonded atoms, thus reinforcing the idea that increased electronegativity directly results in more robust ionic interactions.
