• • Bell ringer: Write the name for FeS.

  • Review ionic compounds

    • How to name

    • How to write formulas

  • Properties of ionic compounds

    • Form when electrons are transferred

    • Must have at least one atom wanting to give electrons (left side of PT) and one wanting to receive electrons (right side of PT)

    • Ionic bonds are formed between charged atoms (ions)

    • Form network structures, not molecules (form into large groups where each atom is attracted to all those around it)

    • Form solids at room temperature

    • Do not conduct electricity unless melted or dissolved

  • Begin covalent compounds

    • Form when electrons are shared

    • Form between atoms that want more electrons (right side of PT)

    • Form molecules (small groups)

    • Can be solid, liquid, or gas at room temperature

    • Do not conduct electricity
