Notes on Naming Ionic Compounds

  • Structure of Ionic Compounds

    • Ionic compounds consist of a metal (first) and a nonmetal (second).
    • Naming order follows the periodic table: the element farther to the left comes first.

  • Prefixes for Number of Atoms

    • Used to indicate the number of atoms in the compound.
    • Examples of prefixes:
    • Mono (1)
    • Di (2)
    • Tri (3)
    • Tetra (4)
    • Penta (5)
    • Hexa (6)

  • Examples

    • For a compound like {\text{BR}}3{\text{O}}8:
    • First prefix (3) yields "tr", and second prefix (8) yields "octo".
    • Combine to form "Trioctoxide".
    • Note: sometimes part of prefixes or element names is dropped for phonetics.

  • Practice and Application

    • Use the provided prefixes to name unknown compounds.
    • Practice helps reinforce the naming convention effectively.
