For Copper, the configuration is a little unsettling — a more stable configuration would be to have 10 electrons in the 3d shell, and this is exactly what we observe! Electron Configuration. Electron cloud build-up was simulated for the different regions (arcs, wigglers, straights) in the rings, considering actual sets of beam parameters and for two different secondary emission yields. Determine the relationship between electron configuration and atomic radius. Discover trends in atomic radii across periods and down families/groups of the periodic table.
