Because of the greater speed of electrons, any dust grain in the vicinity gets bombarded with more electrons than +ions. And those electrons are absorbed into the electron cloud of the dust grain, which can typically host as much as 1 extra electron per million nuclei.

Hi Charles. Does this mean a dust grain typically contains about a million atoms with one extra electron? I don't understand why you say "per million nuclei" instead of "per million atoms". Your Figure 2 shows one negative dust grain with dozens of positive nuclei. Right?
