<P>These popular molecular modelling sets can be used to make many different molecules. This makes them ideal for student use and also for educators and researchers.</P><P>The set contains 72 colour-coded atoms, 105 links and 5 lone pair electron clouds. The shorter links can be used for single bonds, while the longer, flexible links can be used for double or triple bonds.</P><P>Using molecular models can help students to visualise concepts such as isomerism through hands-on learning. The models can also be used to learn about balancing equations and molecular geometry.</P><P>Molymod is a registered trade mark of the EU ( and other places) and is owned by Spiring Enterprises Limited who are the inventors and exclusive manufacturers of the molymod system.
