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

Learn about the structure of diamond, graphite, the metals (iron, copper, magnesium), sodium chloride, cesium chloride, zinc blend, wurzite, rutile, ice and layered structures. Suitable for a student, teacher, researcher or a small group. Includes instructions/activity book.
