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, Study the structures of diamond, graphite, metals (iron, copper & magnesium), sodium chloride, zinc blende, wurzite, caesium chloride, rutile, ice, orthoboric acid, cadmium chloride and cadmium iodide. Make sizeable models of up to 100 atoms in each or multiple smaller models. Includes 5 instruction/activity booklets.Scale: 2 cm = 0.1 nanometer (1 A), MinitATOMS:. 2-prong linear: Hydrogen, white (125). 2-prong 155: Oxygen, red (30). 2-prong 141: Oxygen, red (30). 3-prong 120: Carbon, black (150), Oxygen, red (150). 3-prong 90, 135: Oxygen, red (30). 4-prong 141, 116: Oxygen, red (30). 4-prong tetrahedral: Carbon, black (175), Oxygen, red (75), Sulfur, yellow (100), Halogen, green (50), Metal, silver (125). 6-prong octahedral: Halogen, green (100), Metal, silver (75). 8-prong cubic: Halogen, green (25), Metal, silver (100). 12-prong: Metal, silver (100)BONDS:. Straw, green, 2.5 cm (640). Straw, green, 1.5 cm (320). Straw, white, 10 cm (35). Straw, white, 3.5 cm (160). Straw, mixed set/26 (5)
