Answer

Brief Explanations:

Protons and neutrons are found in the nucleus of an atom and have nearly the same mass (proton mass ≈ 1.6726219 × 10⁻²⁷ kg, neutron mass ≈ 1.674927471 × 10⁻²⁷ kg). Electrons are much lighter, with a mass of about 9.10938356 × 10⁻³¹ kg.

Answer:

Protons and neutrons have nearly the same mass, while electrons are much lighter.
