Which answer choice best explains why uranium-238 can be used in power plants to generate electricity? nuclides of uranium-238 decay over time. They release large amounts of energy as their nuclei break apart. Nuclides of uranium-238 are extremely stable. They can absorb large amounts of energy without breaking apart, so they rarely need to be replaced. Because atoms of uranium-238 have many more electrons than protons, they release steady streams of electric current. Because atoms of uranium-238 have many more protons than neutrons, they attract large numbers of electrons from the surrounding environment.
