Monday, January 13, 2014 Warm Up:1. Write the Formulas:
A. Sodium/ChlorineB. Calcium/SulfurC. Aluminum/Nitrogen
2. Write the Names:A. BeBr2
B. K3PC. B2O3
3. Write the Formulas:A. Lithium PhosphideB. Cesium SulfideC. Barium Bromide
4. 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+3
Common Oxidation Numbers for Transition Metals:
Rules for naming Transition Metals:
1. The name of the metal ALWAYS comes first: The metal’s name is as it is on the periodic table Identify the metals charge with Roman Numerals
2. The name of the nonmetal ALWAYS comes second. Change the ending of the nonmetal to “ide”
3. Unswap and Undrop Bring 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.
FeCl3
Let’s Practice:Compound: Metals symbol
and original oxidation number
Nonmetals symbol and original oxidation number
Is the nonmetal oxidation number correct?
Name of the compound
Ag3N Ag+1 N-3 Yes Silver (I) Nitride
CoBr2
CrI6
Ti3N4
Hg2O
ZnF2
Naming transition metals:1. Name the metal2. Name the nonmetal3. Unswap and Undrop4. Check the oxidation number
FeO Fe+1 O-1
Oxygen’s oxidation number is -2.
5. Multiply to get Oxygen to it’s -2 oxidation number- multiply both Fe and O by 2 to get: Fe+2 and O-2
6. Now name it:Iron (II) Oxide
What is Oxygen’s oxidation number?
Let’s 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?
Name of the compound
NiO Ni+1 O-1 No (by 2) Nickel (II) Oxide
CrO3
Ni3N2
CuO
MnN
Cu2O
PtS2
Writing Compounds from the Name with Transition Metals:1. Write out the ions and their charges for each
elementRemember the charges for the transition metals is written in Roman Numerals
2. Drop the signs3. Swap the numbers4. Simplify if needed
Copper (III) NitrideCu+3 N-3
Cu3N3 CuN
Let’s Practice:Name: Metal
Symbol and charge
Nonmetal symbol and
charge
Compound Simplified compound
Iron (III) Oxide Fe+3 O-2 Fe2O3 N/A
Molybdemum (II) Phosphide
Vanadium (I) Sulfide
Chromium (IV) Chloride
Silver (I) Sulfide
