Where do you find the transition metals?Naming Ionic Compounds with Transition Metals Transition Metals:Metals found in the D-block on the periodic table
Get there name because most do NOT have only 1 oxidation state like the metals in S and P blocks.
Most have 2 or more oxidation states that they transition in and out of.
Fe+2 and Fe+3Common Oxidation Numbers for Transition Metals:
Rules for naming Transition Metals:The name of the metal ALWAYS comes first:The metals name is as it is on the periodic tableIdentify the metals charge with Roman NumeralsThe name of the nonmetal ALWAYS comes second.Change the ending of the nonmetal to ideUnswap and UndropBring the subscripts back up to the opposite element (the elements should now have their actual oxidation number)Double check the nonmetals (anions) oxidation number to make sure it is what it is supposed to be.
FeCl3Lets Practice:Compound:Metals symbol and original oxidation numberNonmetals symbol and original oxidation number
Is the nonmetal oxidation number correct?Name of the compoundAg3NAg+1N-3YesSilver (I) NitrideCoBr2CrI6Ti3N4Hg2OZnF2Naming transition metals:Name the metalName the nonmetalUnswap and UndropCheck the oxidation numberFeO Fe+1 O-1 Oxygens oxidation number is -2.
5. Multiply to get Oxygen to its -2 oxidation number- multiply both Fe and O by 2 to get: Fe+2 and O-26. Now name it:Iron (II) Oxide
What is Oxygens oxidation number?Lets Practice:Compound
Metals symbol and original oxidation number
Nonmetals symbol and original oxidation number
Is the nonmetal oxidation number correct? If no, what do you need to multiply by to fix it?
