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.
2color 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
components are easy to assemble and are
includes a separate booklet of
instructions and a carrying case.
