Honors Chemistry Podcast 4.2

Chemical Nomenclature and

Formula Writing


Ionic Compounds

  • Formed from metals losing electrons to nonmetals resulting in ions of opposite charges.

    NaCl


Formation of Ions


Formation of Ions


Nomenclature (naming)

  • Metal ion always goes first

  • Nonmetal ion changes name ending to –ide

    NaBr

    CaCl2


Name the following ionic compounds

  • Li2S

  • K3P

  • CaO

  • Sr3N2

  • MgI2


Formula Writing

  • Metal (positive ion) first

  • Balance charge of ions to form a neutral compound

  • Examples:

  • Magnesium nitrideSodium Sulfide


Formula Writing

  • Write formulas for the following compounds:

  • Magnesium nitride

  • Potassium chloride

  • Lithium Sulfide

  • Rubidium oxide


Transition Metals

  • Elements with more than one possible charge (oxidation state)- use Roman numerals in name

  • Fe2(SO4)3

  • FeSO4

  • CuO

  • Cu2O


Transition Metals

  • Write the formula for the following:

    Manganese (II) oxide

    Cobalt (I) phosphide

    Titanium (II) bromide

  • Name the following:

    CuCl2

    NiBr

    AuCl3


Polyatomic Ions


Polyatomic Ions

  • Name the following:

    Na2SO4

    K3PO4

    Mg(OH)2

  • Write the formulas for the following:

    Titanium (II) hydroxide

    Potassium sulfite

    Calcium nitrate
