Calcium Iodide Ionic Or Covalent

The compound calcium iodide is ionic. It consists of a metal, calcium, and a nonmetal, iodine, which typically form an ionic bond due to the large difference in electronegativity between the two elements. In calcium iodide, calcium donates electrons to iodine, resulting in the formation of positively charged calcium ions and negatively charged iodide ions. These ions are held together by strong electrostatic forces, forming an ionic lattice structure.
