Question

Quizplus · Accepted Answer

The mass of an electron is much smaller than the given value (9.11 × 10^-31 kg), so option A can be ruled out. The given mass is close to the mass of a proton (1.67 × 10^-27 kg) and a neutron (1.69 × 10^-27 kg), but it is not exact. This suggests that the particle in question is a combination of protons and neutrons, which make up the nucleus of an atom. Therefore, option D is the best choice.
