Hunter, “Chemistry Laboratory Manual (CHEM 162)”, Michigan State University. Ionic compounds can form from transition metals. Transition metals do not always follow the patterns that we discussed. Can have more than one oxidation number (charge. ). To identify the charges of transition metals, roman numerals are placed in their name, directly after the transition metal. Chemical Reactions.
