We’re being asked to classify each given compound as either ionic or molecular.
Let’s first differentiate an ionic compound and a molecular compound.
• Ionic Compound
▪ composed of a positive ion called a cation connected to a negative ion called an anion.
▪ positive ions (cations) are usually metals and negative ions (anion) are usually nonmetals
metal + nonmetal = ionic bond
▪ cations and anions can also be polyatomic ions (example: NH4+, CH3COO-, SO42-)
• Covalent or Molecular Compound
Classify each of the following compounds as either ionic or molecular.
