Final answer:

Protons and neutrons are the most similar in mass within an atom, while electrons are significantly lighter.


Explanation:

Protons and neutrons are the two particles most similar in mass within an atom. They both have a mass of approximately 1 atomic mass unit, making them almost equal in mass.

On the other hand, the electron is significantly lighter than both the proton and neutron, with a mass about 1/2000th of a proton or neutron.
