Click on Nomenclature.
You will do 5 types of compounds listed on this page.
1) binary ionic compounds with fixed charge cations
2) binary ionic compounds with variable charge cations: Stock System
3) ternary ionic compounds containing a polyatomic ion
4) binary molecular/covalent compounds with Greek Prefixes
5) acids
For each of these sections you should do both directions:
Name  formula
and
formula  name
Try a few of the practice problems on each page, but don’t spend too
much time because you will only have this one day in the computer lab.
We will go over all of these rules again in class next time  the point of
this is to see it and try it on your own.
Let’s get started!
Section 1 – Binary Ionic Compounds with Fixed Charge Cations
1. Define CATION and ANION
2. Define Binary Compound:
3. Complete the following points:
1. The order for names in a binary compound is
___________________________________
2. Use the name of cation with a fixed oxidation state
_______________________________
3. The name of the anion will be made from the
_____________________________________
4. Show yourself two examples of how to write the name from the
formula for these type of compounds.
5. Try these practice problems, then check your answers:
1) MgS
2) KBr
3) Ba3N2
4) Al2O3
5) NaI
Part II, name to formula
6. Complete these points to remember:
1. The order in a formula is
________________________________________________________
2. You must know the charges associated with each cation and
anion.
3. The sum of the positive charge and the sum of the negative
charges _________________________
4. You _________________________________________of the cations or
anions to get a total charge of zero.
5. You _____________________________________________________ to get a
total charge of zero.
7. Write the rules/examples for writing the formula of:
Barium iodide
Aluminum oxide
8. Practice with these problems then check your answers:
1) magnesium oxide
2) lithium bromide
3) calcium nitride
4) aluminum sulfide
5) potassium iodide
Section II-Binary Ionic Compounds with Variable Charge Cations –
Stock Sytem
9. Complete the following steps:
Step #1 - the first part of the name is the _________________________
Step #2 - the result from step one ________________________________
Here is how to determine its value:
1. multiply ____________________________________________
2. divide this result by____________________________________
This is the value of the Roman numeral to use
3. The value of the Roman number represents
______________________________.
Step #3 - the anion is named in the usual manner of stem plus
"ide."
10. Write examples for:
CuCl2
Fe2O3
11. Practice with these then check the answers:
1) NiS
2) PbBr4
3) Pb3N2
4) Fe2O3
5) FeI2
12. What is unusual about Mercury I? Peroxide?
Part II, name to formula
13. Complete the following steps:
Step #1 - the first word tells you the ______________________________
Step #2 - the Roman numeral WILL tell you ______________________
Step #3 - the anion symbol and charge comes from the second
name
Step #4 - remembering the rule that a formula ___________________.
14. Write yourself examples of:
copper(I) oxide

16. How will you recognize this type of compound?
17. How should parentheses be used?
18. Write two steps for determining the formula:
step 1:
step 2:
19.
