VisChem topic 6: molecular structure, shape and polarity

This web page contains ten animations of molecules and compound ions as well as nine QTVR objects showing organic molecules. The animations rotate the molecules to show their structure fully. The QTVR objects can be manipulated by the user so that, as well as being rotated, different ways of modelling the molecules can be seen.

The radioactivity of everyday things

Everyday products that contain radioactive elements such as radium may also be radioactive. Elements like uranium and radium become radioactive when the nucleus of the atoms undergoes radioactive decay. In this clip, a scientist challenges people to identify which products, such as brazil nuts and a smoke alarm, are radioactive. ...
