Answer:Barium fluoride (BaF₂) has an ionic bond. Here's why: - Barium (Ba) is a metal and has a tendency to lose two electrons to achieve a stable electron configuration. This makes it a cation with a +2 charge (Ba²⁺).- Fluorine (F) is a nonmetal and has a tendency to gain one electron to achieve a stable electron configuration. This makes it an anion with a -1 charge (F⁻). The electrostatic attraction between the positively charged barium cation (Ba²⁺) and the negatively charged fluoride anions (F⁻) creates the ionic bond in barium fluoride.
