This 220-piece molecular model kit creates up to 65 atoms and is neatly organized in a 13.5" x 9.5" x 3.25" storage case. The kit allows construction of both simple and complex organic and inorganic molecular structures with single, double, and triple bonds. The multifaceted atom pieces support complex geometric arrangements including trigonal planar, tetrahedral, bent, and trigonal pyramid configurations, with some pieces featuring multiple holes on each side. The kit includes an instructions booklet, a removing tool, hydrogen atoms, carbon atoms, nitrogen atoms, oxygen atoms, fluorine atoms, chlorine atoms, and various joint types for bond connections.
