This set contains sufficient parts to make eight atomic models
Each model is an example of the different orientations of the bonds and cover co‐ordination numbers 1 to 6
The atom cores are represented by the standard Molymod® atom parts, and the atomic and molecular orbital parts by colour‐ coded, matt or pastel‐coloured pieces
Lone pairs are represented by brown spheres or brown pear shaped parts
The latter is useful as protonated models of NH4+ and H3O+ may be built thus demonstrating Acid/Base theory
