All of my questions that follow revolve around the question of atomic geometry/structure as it relates to quantum mechanics. On every high resolution (1 angstrom, and a few less than 1 angstrom) TEM image I have seen, atoms appear as spheres. I then found a website that claims it has visualized transits of electrons. The same website even has a related video that shows what is claimed to be electron orbitals, which show an animated, temporally dilated snapshot of electron orbits as concentric rings. The imaged atom in question was supposed to be a krypton atom. My driving question is: What is the exact physical real-life structure of an atom? The finite points of the question are: Is the spherical image of an atom seen in TEM the result of superposition? Or, ... is it the result of electron(s) moving faster than the measuring TEM can differentiate temporally (like motion blur with a camera)? The concentric rings of the imaged atom in the animated experiment have a specific thickness that can be seen. Does this imply a radius or volume to the otherwise point particle electron? Can someone explain why the animation is in concentric rings and not as pixellated vertices or arcs? They claim their method is faster than the transit of a single electron around the nucleus, yet in the image it shows up as a ring, why? Their statements imply that the electron is a particle; what is the electron? A field? A wavelet? A concentric string/ring/shape? A cloud? Or is it a discrete particle as they imply? Aren't they, in actuality, creating controlled interference between a photon and electron wave and using a second photon wave to sample the divergent wave and labeling the attosecond sample as a particle?
