About This Product
Students pick atoms by colour and number of holes, for example one black four-hole carbon and four white one-hole hydrogens for methane, and join them with links chosen for the model type. The set covers simple molecules through aromatic rings, polymers and crystal lattices, and helps with isomerism, stereochemistry and molecular symmetry. Using the removal tool rather than bending links protects the sockets.
Frequently Asked Questions
How should the Atomic Model Set be taken apart?
Slide the link removal tool under the bond and lever the connector straight out, rather than pulling or bending links sideways.
Which links are used for double bonds?
The long flexible links, which are also used for ring-strain molecules such as cyclopropane.
