Radial and Angular Electron Vibrations in a 'Newtonian' 2-D Atom
[more on distance and direction] An electron in a "2D atom" has two degrees of freedom. In this example we use the two dimensions of distance and angle:
distance from the nucleus accounts for a radial vibration, and
direction from the nucleus accounts for an angular vibration.
The 'Radial' and 'Angular' options in the 'Control Panel' isolate these two 1-dimensional vibrations for you.

The two possible senses of rotation, 'counterclockwise' and 'clockwise', are responsible for the concepts of
electron orbital angular momentum,
electron orbital magnetism and
photon absorbtion/emission
so important among atom properties.
