Tape and Tetrahedra
John W. Hill
University of Wisconsin-River Falls, River Falls, WI 54022
Cover
June 1996
Vol. 73 No. 6
p. 531
Abstract
Ball-and-stick models are often used to represent the shapes of molecules, but students frequently have problems relating what they see to the words we use to describe those shapes. I have found a simple solution to the problem of visualizing the tetrahedron (this can be applied to other molecular geometries and electron-pair geometry). I use masking tape or labeling tape to connect the hydrogen atoms to one another. The tape represents the edges of the tetrahedron; the four hydrogen atoms are the corners. This short article describes the procedure.
