Summary of Naming Ionic and Molecular Compounds | How to Pass Chemistry

Main Ideas and Concepts

• Types of Compounds:
  • Ionic Compounds: Consist of one metal and one nonmetal.
  • Covalent (Molecular) Compounds: Consist of two nonmetals.
• Identifying Charges: Students must memorize the charges of common elements to balance charges in Ionic Compounds.
• Naming Ionic Compounds:
  • Without Transition Metals: Name the metal followed by the nonmetal ending in "ide."
  • With Transition Metals: Name the metal, include a Roman numeral indicating its charge, followed by the nonmetal ending in "ide."
  • With Polyatomic Ions: Name the metal followed by the polyatomic ion (which may end in "ate" or "ite").
  • Mixing Transition Metals and Polyatomic Ions: Name the transition metal with a Roman numeral and then the polyatomic ion.
• Naming Molecular Compounds: Use Prefixes (mono-, di-, tri-, tetra-, penta-, etc.) to indicate the number of atoms of each element, followed by the nonmetal name ending in "ide." No charge balancing is required for Molecular Compounds.

Methodology and Instructions

• Identifying Compound Type: Determine if the compound is ionic (metal + nonmetal) or molecular (nonmetal + nonmetal).
• Naming Ionic Compounds:
  • Ionic Compounds without Transition Metals:
    • Identify the metal and nonmetal.
    • Use the nonmetal name ending in "ide."
  • Ionic Compounds with Transition Metals:
    • Identify the transition metal and its charge (using Roman numerals).
    • Follow with the nonmetal name ending in "ide."
  • Ionic Compounds with Polyatomic Ions:
    • Name the metal and the polyatomic ion without "ide."
  • Mixed Ionic Compounds:
    • Name the transition metal with a Roman numeral and the polyatomic ion.
• Naming Molecular Compounds: Use Prefixes for the number of atoms:
  • 1: mono-
  • 2: di-
  • 3: tri-
  • 4: tetra-
  • 5: penta-
  • 6: hexa-
  Combine Prefixes with nonmetal names ending in "ide."

— 00:00 — « This is a very VERY important lesson today, because you will be naming compounds until the end of the semester and if you decide to continue with chemistry, you'll be naming compounds forever. »

— 09:00 — « For covalent compounds do not balance charges. »

— 10:32 — « Now I hope you don't plan on leaving here without practicing what you just learned. »
