Although this simile is now known to miss the mark, its historical importance cannot be denied. The centrifugal force victoriously opposes the electrical attraction and conversely, for each electron. A wonderful merry-go-round (dynamical equilibrium) is the result. In this idyllic version, the revolving motion of the electrons would go on forever, if the atom were not subjected to external infiuences, namely, collisions with other atoms, electrons and photons. Deformed to varying degrees by these impacts, atoms always tend to restore themselves in the most harmonious way, evacuating the excess energy acquired from the collision. 

FIGURE 13.4. Of many possible mechanisms for liquid aerosol formation, four of the most common include (a) surface impact of a high-pressure liquid stream, (b) the collision of high-velocity liquid and gas streams, (c) high-pressure spray nozzles, and (d) spinning-disk centrifugal atomizers.
