Function and Applications

Create 13 model geometries predicted by VSEPR theory with the demonstration-size VSEPR theory kit. With these highly viable models illustrate the basic molecular shapes that are a result of electron repulsion. The following model geometries and variants can be created (as many as 6 simultaneously): linear, trigonal planar, angular, tetrahedral, trigonal pyramidal, angular (2 lone pairs), trigonal bipyrimidal, seesaw, T-shaped, linear (3 lone pairs), octahedral, square pyramidal, square planar. The specially designed "quick change" receptor allows for easy transition to other VSEPR predicted structures. These large models - the atomic centers have a diameter of 7.5 cm resp. 5 cm - are easily seen within the classroom or lecture hall.
