C) Electronegativity of an atom is it's ability to lose electrons during cation formation.
D) Electronegativity of an atom is it's ability to share electrons during a covalent bond formation.
Answer & ExplanationAnswer: B) Electronegativity of an atom is it's ability to attract electrons during bond formation.
Explanation:
Electronegativity, is a chemical property that describes the tendency of an atom to attract a shared pair of electrons (or electron density) towards itself.
