You must take a look at the animation on right side of page, about half way down.
The caption reads: "Slow-motion replay of valence electron motion. Time has been "magnified" by a factor of approximately 10^15 in this sub-atomic-resolution "time microscope" to make this intra-atomic "dance" perceivable to human observation." http://www.attoworld.de/Home/newsAndPress/BreakingNews/index.html#2011-03-13 _snlde Depending on when the 'strobe light' hits it, the electron looks like either a figure-8 or a toroid! I think this is one reason why current models are only partially accurate. because it's a dynamical entity whose 'physical' or 'charge' extent is oscillating between two or more 'shapes'. I would assume that the extent of the vertical oscillation is across the entire diameter of the atom. -Mark
