Monday, January 13, 2014 Warm Up:

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
