If I were to scale up an atom until it were the size of a sports arena, the space filled by the positive charges inside the atom (according to the work of Ernest Rutherford early in this century) would be:
A) as big as the entire stadium (and very thinly spread out)
B) as big as the space filled by all the negative charges (that's why the atom is neutral)
C) very small (perhaps the size of a soccer ball) and in the middle
D) an extremely thin layer spread completely around the outer walls of the stadium
E) this question cannot be answered (even roughly) without knowing how many electrons the atom has
