Ionic Compounds Involving Transition Metals Formulas & Nomenclature

Objectives Covered Today 9. Name compounds containing transition metals. 10. Given the name of a compound containing a transition metal, write its formula.

Objective 9 Transition metals are those metals whose valence electrons exist in the d-block of the periodic table. This allows them to have multiple oxidation numbers We must take this into consideration when naming transition metal ionic compounds
