Chemical Bonding POGIL
Activity 3 - What's in a name?
Objective: Identify some simple rules about nomenclature (naming).
The Model:
Examine the table below, and answer the following questions.
Table 2
Cation Anion Chemical Formula Compound Name
Na+ Cl- NaCl sodium chloride
+2 -2
Ca O CaO calcium oxide
Zn+2 Cl- ZnCl2 zinc chloride
Li+ S-2 Li2S lithium sulfide
+ -3
K N K3N potassium nitride
Reviewing the Model
1. Are ALL cations positive ions or negative ions?
2. Are ALL anions positive ions or negative ions?
3. What is the name of the compound formed by the combination of Li+ and S-2 ions?
Exploring the Model
4. When the name of the ionic compound is given, which ion is stated first?
5. Compare the first part of the compound name to the name of the element from the periodic table. How
does the name of the cation correspond to the name of the element?
6. Compare the second part of the compound name to the name of the element from the periodic table.
How does the name of the anion correspond to the name of the element?
7. From what part of the periodic table do the cations in the Model come (metals or nonmetals)?
8. From what part of the periodic table do the anions in the Model come?
Exercising Your Knowledge
9. For each of the following, predict whether the ion will likely be a cation or an anion.
a. Magnesium ion c. Bromide ion
b. Selenide ion d. Cesium ion
10. For each ionic compound, identify the cation and the anion.
a. Sodium fluoride c. Lithium iodide
b. Strontium sulfide d. Barium chloride
11. In what way did the name provide clues about the classification of each element as a cation or anion?
12. Where on the periodic table would you expect to find elements that ionize to form cations?
13. Where on the periodic table would you expect to find elements that ionize to form anions?
Summarizing Your Thoughts
14. Consider the clues you identified, and write a general rule for how you change the name of elements to
cations when naming ionic compounds.
15. Consider the clues you identified, and write a general rule for how you change the name of elements to
anions when naming ionic compounds.
16. Given the chemical formula of an ionic compound, list at least three necessary steps to give the correct
name of that compound. (If needed, use a chemical formula of a compound from the table above as an
example in listing the naming steps.
