1. Rules. Quickly review the rules for the following:
- Naming Elements (easy)
- Naming Covalent Compounds
- Naming Cations
- Naming Anions
- Polyatomic Ions
- Other / Misc.
2. Decision Tree. We’re going to map out how to decide which nomenclature rules to use for a given chemical formula.
a. If you are given a chemical formula, how do you decide if it’s an element, covalent compound, or ionic compound?
Examples: Br2, NaCl, LiBr, NaNO3, CCl4, CO2, CO32-
Covalent Compound
Ionic Compound
- What rules / information do you need when dealing with formulas of elements? What pages can you find this information on?
Rules / Information
Book Pages / Figures / Tables
- What rules / information do you need when dealing with formulas of covalent compounds? What pages can you find this information on?
Rules / Information
Book Pages / Figures / Tables
- If you have the formula of an ionic compound, how do you decide which special information applies?
Simple Ionic Compound
Transition Metal Ions
Polyatomic Ions
- How do you name simple ionic compounds?
Simple Ionic Compounds
- Quickly summarize the stock & classic naming systems for transition metal ions.
Stock System
Classic Names / (clarify –ic, -ous)
3. Polyatomic Ions (also part of the decision tree)
- Define the term polyatomic ion. Make sure you explain how the charge is spread over the whole molecule.
- If an ionic compound has a polyatomic ion, what types of bonds are present?
- What are the formulas for the two positively charged polyatomic ions?
- Fill in the table for the 5 “normal” polyatomic oxyanions.
Formula / Name / # of Oxygens / Charge
NO31-
ClO31-
CO32-
SO42-
PO43-
- Describe the difference between –ate and –ite.
- Halogen oxyanions can have 1, 2, 3, or 4 oxygen atoms in them. Answer the following.
What is the normal number (-ate)?
What is the formula for chlor–ite?
How do you name the anion with 1extra oxygen?
How do you name the anion with 2fewer oxygens?
- Can you have an ionic compound without any metals in it? (NH4+)
4. Other.
- Which misc. polyatomic ions do we need to know?
- We won’t focus on them but read / understand the hydrides & hydrates..
When you finish these questions, transcribe them to the big concept map.
Of course there’s more to know but this is enough to do in 1 day’s class.
