&
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
