👉 Electronegativity is a physical property of atoms that refers to their tendency to attract electrons more strongly than other atoms. Electronegativities are usually expressed in units called atomic masses, and they can be positive or negative. The higher an atom's electronegativity value is, the greater its attraction for electrons compared to other atoms. This can lead to a situation where atoms with high electronegativity values tend to have more stable structures than those with lower electronegativities
