(Physical Science) A simulation at the nuclear level has nuclei with 20 protons and 100 neutrons. Alpha particles can get very close to the nuclei. When the nuclei have 100 protons and 20 neutrons, the alpha particles cannot get as close to the nuclei. The nucleus is the same size in both scenarios. Why does the motion of the alpha particles differ? (1 point)

A. Neutrons repel the particles, while protons do not.

B. Protons repel the particles, while neutrons do not.

C. Neutrons attract the particles, while protons do not.

D. Protons attract the particles, while neutrons do not.​
