Learners assign oxidation numbers to atoms in neutral compounds and in polyatomic ions. Six examples are worked through in detail, and three problems are provided.
Dr. Miriam Douglass
Dr. Martin McClinton
Learners examine the periodic table to identify metallic elements that have either fixed or variable oxidation states.
Learners examine the meaning of oxidation, reduction, and half-reaction, and watch a film showing the deposition of copper metal from the reduction of copper (II) ion by aluminum. A brief quiz completes the activity.
Roman numerals are used to identify the charges on metal cations having multiple oxidation states. Five examples are provided for practice.
Learners examine a table containing the names of common cations and anions.
