The following interactive activities were produced by the University of Oxford's Technology-Assisted Lifelong Learning (TALL) unit (www.tall.ox.ac.uk).

Investigating the relationship between electronic energy levels and atomic spectra
Chapter 3

This activity includes a Lab Mode and a Test Mode. Use the Lab mode to explore how the hydrogen atomic spectrum is related to transitions between the electonic energy levels of the hydrogen atom. Then try the multiple choice quiz to see whether you understand the principles involved.

Combining atomic orbitals to form molecular orbitals
Chapter 4

This activity includes a Lab Mode and a Test Mode. Use the lab mode to explore how the s and p orbitals on two atoms combine to form molecular orbitals. Then try the multiple choice quiz to see whether you understand the principles involved.

Acid and base titrations
Chapter 7

This activity includes two Lab Modes, in which you can see the effects of varying indicator and concentration, and a Test Mode in which you can test your understanding.
