Multiple choice questions

Try the following multiple choice questions to test your knowledge of this chapter. Once you have answered the questions, click on 'Submit Answers for Grading' to get your results.

If your lecturer has requested that you send your results, please complete the routing information found at the bottom of your graded page and then click on the 'E-Mail Results' button. Please do not forward your results unless your lecturer has specifically requested that you do so.

For some of these questions, you need data from the appendices of Inorganic Chemistry, third edition. On opening the book cover you will find a Periodic Table and a list of elements and atomic masses. Physical constants are listed on the back inside cover of the book.
