Description

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 the 8 and 12 coordinate atom centres within this set to build models of diamond, graphite, sodium chloride, 8 and 12 coordinate metals, caesium chloride, fluorite, zinc blende, wurzite, rutile and ice. Includes 5 instruction/activity booklets.
