An extensive model system offering 15 atomic bonding configurations in 12 colours of plastic atoms. The carbon atom is represented in nine configurations: linear, trigonal (in five angle variations), tetrahedral, octahedral, trigonal-bipyramidal. . Spare atom centres and bonding tubes are available for all model kits.
