Summary of Ionic Compounds

•Transition metals “transition” because they can form many different ions

•Iron as a transition metal can be Fe²⁺ or Fe³⁺

•Because you can’t determine the oxidation number from the periodic table, a Roman Numeral is used to show it

copper (I) ®

copper (II) ® Cu²⁺

​Cu¹⁺

1.Write the name of the first element (the metal)

  Exception #2: if a transition metal, include a   Roman numeral to indicate the charge of the  metal

2.Write the name of the second element (the nonmetal) with an –ide ending

    Example:

  CuCl Copper (I) Chloride

1.Write down the ions of each element with charge (The transition metals charge will be given by the use of Roman Numerals.)
Iron (II) Oxide

2. criss cross applesauce

3. Write down the formula using subscripts

 Fe2O2

4. Reduce/simplify (if needed)

FeO
