Oxidation States

The Oxidation States Concept Builder assesses students' ability to determine the oxidation number of an element in a species. Each question involves the same task - a formula is presented and students must determine the oxidation number of one or more elements present within the formula. There are a total of 60 questions in this Concept Builder. They are organized into 16 different Question Groups and spread across the three difficulty levels. Question-specific help is provided for each of the 16 situations. Questions in the same Question Group include identical types of formulae. The built-in feedback and help makes this Concept Builder a great study tool. When used with our Task Tracker program, it is a great tool for use as an in-class or out-of-class assigned task.
