E)none of the above

Question

Quizplus · Accepted Answer

The size of an atom is not significantly influenced by its mass or the number of nucleons, but by the electric charge of its nucleus. A higher nuclear charge (more protons) in heavy atoms pulls electrons closer, which can offset the size increase expected from having more electrons.
