Molymod® Molyorbital™ 8 model Collection Set

This set contains sufficient parts to make the eight atomic models shown in the photograph. The different shapes are examples of the orientations of the bonds and cover coordination 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 H3O+ as a result of the migration of H+ from hydrogen chloride.

Models included:

• Co-ordination 1. Hydrogen chloride HCl - linear
• Co-ordination 2. Beryllium chloride BeCl2 - linear
• Co-ordination 3. Water H2O - bent
• Co-ordination 4. Boron trihydride BH3 - trigonal planar
• Co-ordination 5. Ammonia NH3 - pyramidal
• Co-ordination 6. Methane CH4 - tetrahedral
• Co-ordination 7. Phosphorus pentachloride PCl5 - trigonal bipyramidal
• Co-ordination 8. Sulphur hexafluoride SF6 - octahedral
