General description

The use of 14, 20,  26-sided polyhedrons as atomic nuclei makes these models unique. The various bond angles  distances needed for the models can be precisely represented,  the symmetrical characteristics of the structures can be observed.
? Color-coded polyhedrons to indicate different elements
? Flexible polyacetal connecting bonds permit easy assembly of complicated molecules  models of strained compounds  distorted crystals
? ? scale provided with sets allows measurement of bond distances
? Bond puller included for easy disassemble
? Two types of orbital plates for p atomic orbitals  π molecular orbitals (some sets only)
