Use the periodic table to determine the electron configuration of dysprosium (dy) and americium (am) in noble-gas notation.

In the millikan oil drop experiment they determined that every drop had a charge which was a while number multiple of -1.60x10^-19. if a drop has a total charge of -9.60x10^-19 then how many excess electrons are contained within the drop?
