Station One:
Types of Compounds
Type I: Ionic Compound
-Has a metal NOT from the transition metal section of the PT and a nonmetal/polyatomic ion.
-Does NOT use Roman numerals in the name
Type II: Ionic Compound
-Has a metal from the transition metal section of the PT and a nonmetal/polyatomic ion.
-Uses Roman numerals in the name
Type III: Covalent Compound
-Made of 2 nonmetals.
-Uses prefixes in the name
Type Acids:
-H is ALWAYS the first element in the compound
-The name always says acid in it!
-If there is NO oxygen in the formula, it’s a binary acid and you HAVE to use the prefix hydro- in the name.
-If there is oxygen in the formula, it’s an oxyacid and it will end in either –ic acid (comes from –ate) or –ous acid (comes from –ite).
Directions: Identify the type of compound for each substance.
- N2O3
- H2CO3
- Aluminum sulfate
- Cobalt (III) nitride
- HBr
- Tetraphosphorousdecoxide
- K3PO4

Station 2: Writing Formulas
Type I: Ionic Compounds
-Write the symbol and charge of the metal, use the periodic table to determine the charge.
-Write the symbol and charge of the nonmetal/polyatomic ion.
-Criss-cross the charges.
- If you cross a number to a polyatomic ion, put the ion in parentheses first.
Type II: Ionic Compounds
-Write the symbol and charge of the metal, the Roman Numerals tell you the charge for the metal
-Write the symbol and charge of the nonmetal/polyatomic ion.
-Criss-cross the charges.
- If you cross a number to a polyatomic ion, put the ion in parentheses first.
Type III: Covalent Compounds
-Write the symbol for the first element; change the prefix to a subscript.

-Write the name of the metal
-Write the name of the nonmetal, change the ending to –ide.
OR
-Write the name of the polyatomic ion.
Type II: Ionic Compounds
-Write the name of the metal.

OR
-Write the name of the polyatomic ion.
Type III: Covalent Compounds
-Write the name of the first element.

- Na2O
- CrI3
- H2O
- CaCO3
- Pd2(SO3)3

Station 4: Acids
Formulas
-Is hydro- part of the name? Then there is NO oxygen in the formula!
- Write H+.
- Write the 2nd element’s symbol and charge.
- Criss-cross the charges.
-If there is NO hydro, does it end in –ic acid or –ous acid?
- If it ends in –ic acid…
- Write H+.
- Write the symbol and charge of the polyatomic ion that ends in –ate.
- Criss-cross charges.
- If it ends in –ous acid…
- Write H+.
- Write the symbol and charge of the polyatomic ion that ends in –ite.

Station 5: Balancing Chemical Equations
Use coefficients to make sure that you have the same number of atoms of each element on the left and right side of the equation! Remember, a coefficient multiples through an entire formula!
Directions: Balance the equations.
- H2O(l) + Ba(s) → H2(g) + Ba(OH)2(aq)
- Na2SO4(aq) + FePO4(aq) → Na3PO4(aq) + Fe2(SO4)3(s)
