Chemistry Cumulative Review Latest Update Graded A+ Electronegativity The tendency of an atom to attract electrons in a chemical bond. It is not directly measurable. Metals have low electronegativity, meaning they do not hold onto electrons tightly and often lose them in reactions. Nonmetals have high electronegativity, meaning they hold onto electrons strongly and often gain electrons from other elements. Covalent Bond The sharing of electrons between two nonmetal atoms. ...
