ObjectiveToday I will be able to:

Correctly name and write the formula for ionic compounds using the classical and stock method

Evaluation/ AssessmentInformal assessment – Listening to group interactions as

they complete the naming and writing formulas worksheets.

Formal Assessment – Analyzing student responses to the exit ticket and naming/writing formulas worksheet

Common Core ConnectionBuild Strong Content KnowledgeLook for and express regularity in repeated reasoning

Standard Naming Rules◦ Write the full name of the metal first◦ Then write the second element, take off the

ending and add the suffix –ide◦ If the second ion is a polyatomic ion, use the full

name of the ion Examples

◦ CaO – Calcium Oxide◦ BaCl2 – Barium Chloride

Exceptions◦ Transition metals can have multiple oxidation

numbers◦ Standard naming rules apply but we need to

account for the oxidation number Two Naming Systems

◦ Classical◦ Stock

Stock method - use a roman numeral◦ Examples

FeCl3 – Iron(III) Chloride FeCl2 – Iron (II) Chloride PbCl4 – Lead(IV) Chloride

Later we will discuss an additional method called the Classical Method

Stock is more standard

Complete the practice at your desk. Ask Mr. Klotz for help if you have questions. We will

review selected responses as a class.

These rules still apply:Then write the second element, take off the ending

and add the suffix –ideIf the second ion is a polyatomic ion, use the full

name of the ion

The name of the metal for the elements in the d-block and f-block changes

Use a latin stemExample: Copper

Stem: Cupr – Cuprous – Cu+1

Cupric – Cu+2

CuCl2 = Cupric Chloride

- ous is associated with the lower oxidation number

- ic is assoiciated with the larger oxidation number

FeCl2Ferrous Chloride

FeCl3Ferric Chloride

Name the ionic compounds containing polyatomic ions using the classical method. Selected responses will be reviewed in class

Complete the practice at your desk. Ask Mr. Klotz for help with the questions.

What’s wrong with the following formula/ name of compound?

Mg2Cl

MgSO4 – Magnesium sulfide

Baride Chlorine
