General description

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

Please see Technical Information Bulletin AL-183 for a listing of these items, available on our website at sigma-aldrich.com

Use this introductory structural chemistry set to build and study models of: sulphur, sodium chloride, diamond, graphite, metals, hydrocarbons, acids and bases, detergents, nylon, water and ice, amorphous structures. Suitable for a student, teacher, researcher or a small group sharing. Includes instructions/activity booklet.
