This plot shows where all the electrons tend to be moving within the silicon nanocrystal. Each electron in the molecule exists in a strangely shaped orbit, but when looking at all the electrons and their orbits, the average is this. Note how the plot looks like the electrons form clouds around all the atoms and in between neighboring atoms. This plot shows the bonds that exist between atoms that hold the molecule together.
