General description

Large, lightweight molecular models for classroom demonstration of organic and inorganic structures. For building models to scale of 20 cm/Å and 8 cm/Å. Bond lengths range from 5.5 to 27 cm. Atomic centers are 5 cm in diameter, finished in standard atom colors, and have a reinforced vinyl receptor at each bond position for insertion of connecting rods (bonds). All model kits include storage box and instructions. Additional atoms and bonds are available separately.

Questions

1–2 of 2 Questions  

  1. For the various giant size molecular model kits, can you list the number of atoms of each element/color/electronic arrangement (tetrahedral, trigonal bipyramidal, octahedral, and/or bent) present in each kit? Also, how many hydrogen atoms?

    1 answer

    1. The Technical Information Bulletin Number AL-194 lists the components of the Basic, Standard and Deluxe Kits. itemizes the quantity of each type of component (atom centers and bonds) included in each of the Giant Molecular Model Kits, and lists the atom configurations.
