Question

an atom contains one proton, one electron, and one neutron. which two particles are most similar in mass? the neutron and the electron the proton and the electron the proton and the neutron the neutron and the atom

Explanation:

Protons and neutrons are located in the nucleus of an atom. The mass of a proton is approximately \(1.6726219\times10^{-27}\) kg, and the mass of a neutron is approximately \(1.67492749804\times10^{-27}\) kg. Electrons are much lighter, with a mass of about \(9.10938356\times10^{-31}\) kg. Atoms are made up of protons, neutrons, and electrons, so their mass is the sum of these particles.

Answer:

the proton and the neutron
