Framework Molecular Model Student Kit

This accurate, reasonably priced molecular model set enables users to represent all atoms having up to 12 electrons in their valence shells -- including those which cannot be built with the most expensive sets (i.e., cyclopropane, cubane, etc.).

• features only two basic components -- metal valence clusters (tetrahedron, trigonal, bipyramid, and octahedron) and plastic tubing -- that allow the representation of any atom of the periodic chart.

• metal valence clusters define bond angles precisely and can be adjusted to construct models of molecules with unusual bond angles.

• color-coded plastic tubing enables clear identification of atoms.

• 2—color tubing of univalent atoms bonded to other atoms shows univalent atoms with correct covalent and van der Wall's radii.

• shows molecular orbitals and electron pair orbitals.

• components are easy to assemble and are reusable.

• includes a separate booklet of instructions and a carrying case.
