Answer

Brief Explanations:

In an atom, protons and neutrons are found in the nucleus. They have approximately the same mass (proton mass is about 1.6726219×10⁻²⁷ kg and neutron mass is about 1.674927471×10⁻²⁷ kg) and are of similar size compared to electrons which are much smaller and lighter.

Answer:

protons and neutrons
