Which substance has ionic bonds?

Question

Quizplus · Accepted Answer

Lithium iodide (LiI) has ionic bonds as it consists of a metal (lithium) and a non-metal (iodine) which have a significant difference in electronegativity. The electronegativity difference creates a transfer of electrons from lithium to iodine, resulting in positively charged lithium ions and negatively charged iodide ions, which are held together by the electrostatic attraction between opposite charges. Br₂, NH₃, and H₂O do not have ionic bonds, as they consist of non-metals that share electrons in covalent bonds.
