Neutrons and protons have almost but not quite the same mass. A neutron is slightly heavier, in fact the mass difference between protons and neutrons equals the mass of an electron. A free neutron not bound into an atomic nucleus is unstable, and will decay back into a proton and an electron. This process is called beta decay because beta rays are energetic electrons.

protons. but really a neutron has a slightly larger mass, a free neutron will decay into a proton, an electron, and an anti electron neutrino after about 15 minutes. so basically the mass of an neutron is about an electron and a neutrino (sooo close to 0 that we cant even tell what their mass, only that they have some mass)

Neutrons and protons have approximately the same mass. As I remember, the difference in their weight is the weight of one tiny electron, the neutron being heaviest.

Protons. But their masses are not EXACTLY equal...a neutron's mass is slightly more. but you can assume they are the same

protons - electrons have mass but it is a minute amount therefore is deemed no mass in equations.
