What happens to the atomic radius when an elctron is lost

Compare and contrast the bohr model and the electron cloud models of the atom.

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?
