Recall the following definition:
• Covalent or Molecular Compound
▪ composed of more than one nonmetal together
▪ nonmetal + nonmetal = covalent bond
• 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-)
