Prediction of Reasonable Ion Charges
Use the nomenclature information available to determine common oxidation states for monatomic ions.• monatomic: contains only one atom• ion: has a positive or negative charge• For a monatomic ion, the oxidation state is
the same as its charge.

Constructing Ions and the Periodic Table
Construct and name at least 10 neutral compounds that can be formed from the following list of atoms.
H O S Na Ca Cr Fe In Pb
Divide up the activity: work on cations or anions.

Constructing Ions and the Periodic Table
Combine cations and anions to make neutral compounds.• Determine the formula and name of each
compound.• Use each cation or anion only once in
making various compounds. Identify and name any molecular,
neutral compound that can be formed.
