Advanced Level Chemistry Molecular Modelling Kit - Molymod002576
Visualize complex molecular structures using high quality plastic moulded spheres and connectors. Each atom of an element is represented by a coloured ball. The number of holes indicates the valency of each atom (in some cases the elements have the ability to bond in more than one way and consequently have more holes). Possible molecular shapes include linear, angular or bent, triangular pyramidal, trigonal planar, tetrahedral, trigonal bipyramidal, and octahedral. Element balls are 2cm in diameter. The exception is Oxygen, which is 1. 5 cm. This kit contains: Spheres - 18 hydrogen, 8 carbon, 7 oxygen, 6 halogen-Cl, 6 halogen-F, 4 nitrogen, 4 sulphur, 4 boron, 4 phosphorus, 6 metal; 3 Pair-shaped electron pair; Links - 26 medium, 12 long flexible. This molecular model set is designed for science use and should not be used for any other purpose. It is not a toy.
