Question

Quizplus · Accepted Answer

Helium nuclei (with two protons) would experience the strongest repulsive electromagnetic force when pushed together, as the force is proportional to the product of the charges of the two nuclei. Helium has more protons (and thus a higher charge) than hydrogen or deuterium, leading to a stronger repulsion between two helium nuclei.
