Allgemeine Beschreibung

Ein umfassendes Modellsystem mit 15 Bindungskonfigurationen und Plastikatomen in 12 Farben. Kohlenstoff in 9 Konfigurationen: Linear, trigonal (in 5 verschiedenen Winkeln), tetraedrisch, octaedrisch und trigonal-bipyramidal. In zwei Größen erhältlich: Minit ind Orbit.

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.
