Final answer:

Protons and neutrons have a mass of about 1.67 x 10-24 grams, while electrons have a much smaller mass. Neutrons and protons are approximately the same size and mass because they both are close to 1 atomic mass unit (amu).


Explanation:

Protons and neutrons have a mass of about 1.67 x 10-24 grams, which is considered one atomic mass unit (amu). In comparison, the mass of an electron is much smaller, about 1/1840 of the mass of a proton or neutron. Therefore, neutrons are about the same size and mass as a proton because they both have a mass close to 1 amu.
