an atom contains one proton, one electron, and one neutron. which two particles are most similar in mass?\no the neutron and the electron\no the proton and the electron\no the proton and the neutron\no the neutron and the atom
Answer
Brief Explanations:
In an atom, protons and neutrons have approximately the same mass. Electrons have a much smaller mass compared to protons and neutrons. An atom's mass is mainly determined by protons and neutrons, but an atom is not a particle comparable in mass to a single neutron in the way the question asks.
Answer:
C. the proton and the neutron
