Which substance has ionic bonds?

Question

Quizplus · Accepted Answer

K₂S has ionic bonds because it is composed of a metal (potassium) and a non-metal (sulfur) which have a large difference in electronegativity, resulting in the transfer of electrons from potassium to sulfur and the formation of ionic bonds. SO₃ is a molecular compound that has covalent bonds, CI₄ is also a molecular compound that has covalent bonds, and N₂ is also a molecular compound that has a triple covalent bond between two nitrogen atoms.
