MODEL ATOMIC ELECTRON REPULSION

This set contains sufficient parts to make eight atomic models as shown in the photograph. The different shapes are examples of the orientations of the bonds and cover co-ordination numbers 1 to 6. Lone pairs are represented by brown spheres or brown pear shaped parts. The 2 extra pear shaped parts are included in the set to enable protonated models to be made, e.g. Acid/Base theory, the formation of H2O⁺ as a result of the migration of H⁺ from Hydrogen Chloride.
