Atomic and Nuclear Physics

Beta particles are high-speed electrons emitted during radioactive decay, which is why option B (Electrons) is correct.

France produces the highest percentage of its electricity from nuclear power plants, generating a significant portion of its energy from atomic reactors, more than any other country. While the USA has more reactors and total nuclear energy production, France relies more heavily on nuclear energy as a share of its total electricity.

Ernest Rutherford discovered the nucleus of the atom through his gold foil experiment, which showed that atoms have a small, dense, positively charged center called the nucleus.
