:Title: Atoms and orbitals
Example drawings to help explain the `VSEPR atom model`_ to high school
students. Although the actual model is three dimensional, these drawings
are deliberately presented as two dimensional to gently introduce them to the
concepts, before advancing to three dimensional models.
