Abstract

A dynamic model of a Bohr atom is described; the model being capable of representing all of the normal and many of the excited configurations of the first eleven elements of the periodic table. The nucleus and all of the electrons are suspended in space on jets of air, and are moving; some in circles and some in paths resembling ellipses. About fourteen important concepts of the Bohr atom are brought out by the model, among them being the electron grouping, the progression of perihelion, the spinning electron and the quantization of the spin axis in space.
