Multiple choice questions

For some of these questions, you need data from the appendices of Inorganic Chemistry, third edition by C.E. Housecroft and A.G. Sharpe. 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.

Multiple choice questions by Catherine E. Housecroft.
