Unit Atom Geometries
SKU: 69175
All of the 45mm atom spheres have multiple holes that can be configured to demonstrate any standard (VSEPR) geometry.
All of the 45mm atom spheres have multiple holes that can be configured to demonstrate any standard (VSEPR) geometry.
The black sphere has been constructed to show a tetrahedral (sp3) shape by using 4 of the 4/8 coordinate bond pegs. The blue sphere has been configured with 2 polar and 3 radial bond pegs to show a trigonal bipyramidal geometry. The silver sphere below has been constructed using 4 radial pegs and 2 polar pegs for an octahedral geometry.
If only one polar peg is used, the sphere can representative a univalent atom. If 2 polar pegs are used, the sphere can represent a 180o linear arrangement (e.g. hydrogen bond). If only three radial pegs are used, then the sphere will represent a trigonal configuration.

Just started using this product, but so far seems pretty good. The instructions are a bit limited and the connections a little more complex than a standard model set, but size is good and quality seems good.
