Final answer:
Electronegativity is the term that describes an atom's ability to attract electrons when involved in a chemical bond.
Step-by-step explanation:
Electronegativity is the term that describes an atom's ability to attract electrons when involved in a chemical bond. It is a measure of the relative ability of an atom to attract shared electrons to itself in a chemical compound. Elements with high electronegativities tend to acquire electrons in chemical reactions, while elements with low electronegativities tend to lose electrons. For example, oxygen has a high electronegativity and tends to attract electrons, while sodium has a low electronegativity and tends to lose electrons.
