Copper iodide is an ionic compound.
Sodium iodide, like all sodium compounds, is ionic.
Covalent
Zinc iodide is ionic
This is kind of a trick question. Solid copper will hold together via metallic bonds, which are something like a group covalent bond. That is, the valence electrons from every Cu nucleus form a "sea of electrons" to stabilize the positive charge.
Potassium iodide is a polar, ionic compound.
