Verified step by step guidance1
Understand the concept of subatomic particles: Subatomic particles are particles smaller than an atom, and they include protons, neutrons, and electrons.
Recognize the mass of each subatomic particle: Neutrons and protons have similar masses, which are approximately 1 atomic mass unit (amu). Electrons have a much smaller mass, approximately 1/1836 of an amu.
Compare the mass of a neutron with other subatomic particles: Since neutrons and protons have similar masses, they are often considered to be nearly equal in mass.
Identify the subatomic particle most equal to a neutron in mass: Given the options, the proton is the subatomic particle that is most equal to a neutron in mass.
Conclude that the correct answer is 'Proton' based on the comparison of masses between the neutron and other subatomic particles.
