3-D Angles
Visualizing three-dimensional structures is a major hurdle for chemistry students. Compounding
the difficulty, chemists use three different concepts to imply geometry, although there is no
obvious geometric information in two of them. The bond angle (a geometric construct) can be known
from noting either the hybridization of the central atom (a quantum mechanical construct) or the
coordination number (the number of other atoms bonded to the central atom).
3-D Angles uses pattern recognition principles introduced through rapid repeated exposure
to three concepts to teach students to intuitively associate the three terms together in order to
be able to correctly recognize the molecular structure from limited information.
Setup program
3-D Angles requires a computer running the Microsoft Windows 8,
Windows 10, Windows 11, or later Windows operating system.
