Let’s first differentiate an ionic compound and a molecular compound.
• Molecular Element
▪ exists anytime the same type of element (nonmetals) are combined together (Example: S8)
▪ Recall the diatomic molecules: H2, N2, F2, O2, I2, Cl2, and Br2
• Covalent or Molecular Compound
Which formulas represent ionic compounds and which represent covalent compounds?
N2, PCl3, NH4+, CS2,
