Chemistry 111 Nomenclature Concept Maps

Chemistry 111 Nomenclature Concept Maps

1.  Rules. Quickly review the rules for the following:

1. Naming Elements (easy)
2. Naming Covalent Compounds
3. Naming Cations
4. Naming Anions
5. Polyatomic Ions
6. 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-

1. What rules / information do you need when dealing with formulas of elements? What pages can you find this information on?

1. What rules / information do you need when dealing with formulas of covalent compounds? What pages can you find this information on?

1. If you have the formula of an ionic compound, how do you decide which special information applies?

1. How do you name simple ionic compounds?

1. Quickly summarize the stock & classic naming systems for transition metal ions.

3.  Polyatomic Ions (also part of the decision tree)

1. Define the term polyatomic ion. Make sure you explain how the charge is spread over the whole molecule.

1. If an ionic compound has a polyatomic ion, what types of bonds are present?

1. What are the formulas for the two positively charged polyatomic ions?

1. Fill in the table for the 5 “normal” polyatomic oxyanions.

1. Describe the difference between –ate and –ite.

1. Halogen oxyanions can have 1, 2, 3, or 4 oxygen atoms in them. Answer the following.

1. Can you have an ionic compound without any metals in it? (NH4+)

4.  Other.

1. Which misc. polyatomic ions do we need to know?

1. 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.
