Based on electronegativities, which one of the following would have ionic bonds?

Question

Quizplus · Accepted Answer

Ionic bonds typically occur between a metal and a nonmetal, with the metal having a lower electronegativity and the nonmetal having a higher electronegativity. In option B, magnesium (Mg) is a metal and chlorine (Cl) is a nonmetal, and their electronegativities differ significantly, indicating the likelihood of an ionic bond. The other options either contain only nonmetals or do not have a significant difference in electronegativity between the elements, indicating covalent or polar covalent bonds.
