What is the mass of a proton relative to a neutron?

• A. Much greater
• B. Much lower
• C. Approximately equal
• D. Significantly smaller

Answer: (C)

The mass of a proton relative to a neutron is approximately equal because both particles are categorized as nucleons, which are the particles found in the nucleus of an atom. Neutrons and protons have very similar masses, with the mass of a proton being about 1.007 atomic mass units (amu) and the mass of a neutron being about 1.008 amu. This small difference indicates that for most practical purposes, we can consider their masses to be roughly the same, hence the term "approximately equal." It's important to note that while protons and neutrons do have slightly different masses due to the fundamental forces and properties of the quarks that make them up, those differences are minimal compared to their overall mass. Thus, when comparing the mass of protons and neutrons, it's accurate to state that they are effectively equal.
