Cochranes molecular models

Descrição detalhada : 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.Scale: 2 cm = 0.1 nanometer (1A), MinitATOMS:. 2-prong linear: Hydrogen, white (25). 3-prong 120: Carbon, black (30), Oxygen, red (30). 4-prong tetrahedral: Carbon, black (35), Oxygen, red (15), Sulfur, yellow (20), Halogen, green (10), Metal, silver (25). 6-prong octahedral: Halogen, green (5), Metal, silver (15). 8-prong cubic: Halogen, green (5), Metal, silver (20). 12-prong: metal, silver (20)BONDS:. Straw, green, 2.5 cm (80). Straw, green, 1.5 cm (40). Straw, white, 10 cm (10). Straw, white, 3.5 cm (20). Straw, mixed set/26 (1)
