The use of 14, 20, and 26-sided polyhedrons as atomic nuclei makes these models unique. The various bond angles and distances needed for the models can be precisely represented, and 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 and models of strained compounds and distorted crystals
Å scale provided with sets allows measurement of bond distances
Bond puller included for easy disassemble
Two types of orbital plates for p atomic orbitals and π molecular orbitals (some sets only)
