Question

Classify each of the following compounds as ionic or molecular CS2 CuO KI PCl3

Answer 1

CS2 is a molecular compound, CuO and KI are ionic compounds, and PCl3 is a molecular compound.

Step-by-step explanation:

The compounds CS2, CuO, KI, and PCl3 can be classified as follows:

• CS2: Molecular compound. This compound is made up of two nonmetals: carbon and sulfur. They share electrons and form covalent bonds.
• CuO: Ionic compound. This compound is made up of a metal (copper) and a nonmetal (oxygen). The metal donates electrons to the nonmetal, resulting in the formation of ionic bonds.
• KI: Ionic compound. This compound is made up of a metal (potassium) and a nonmetal (iodine). The metal donates electrons to the nonmetal, resulting in the formation of ionic bonds.
• PCl3: Molecular compound. This compound is made up of a nonmetal (phosphorus) and a halogen (chlorine). They share electrons and form covalent bonds.
