About This Product
This model set illustrates how electron pair repulsion determines the shapes of molecules, with each model showing a different orientation of bonds. Lone pairs are represented by brown spheres or pear-shaped parts, and protonated models of the ammonium and hydronium ions can also be built to demonstrate acid/base theory.
