An electrons position cannot be known precisely only it's probability of being in a certain location can be known

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?

Consider the four elements above. which one of these elements will combine with oxygen in a 1: 1 ratio?
