Neutrons and protons have mass 1 (relative to proton, given the value of 1).
Electrons have mass 1/1840 (relative to proton, given the value of 1).

Protons and neutrons have almost the same mass.
Neutrons and protons are both subatomic particles found in the nucleus of an atom. They have similar masses and are both composed of smaller particles called quarks.
"All subatomic particles have the same mass" is not a true statement, as different subatomic particles, such as protons, neutrons, and electrons, have different masses and charges.
neutrons and protons
The neutron and the proton have masses close to 1 amu.
Subatomic particles with no mass are called neutrinos. Neutrinos are elementary particles that have extremely small, non-zero masses, but they are considered nearly massless in many calculations due to their very small mass values.
The three lightest subatomic particles are electrons, neutrinos, and photons. Electrons and neutrinos have very small masses, while photons are massless.
Proton and neutron (components of the atomic nucleus) have masses very close.
They have different masses, electrical charge, dimensions, life time, spin etc.
Particles of similar mass are often contained within atomic nuclei, where protons and neutrons reside. These nucleons have comparable masses and are held together by the strong nuclear force. Additionally, in particle physics, similar mass particles can be found in various subatomic particle families or groups, such as mesons and baryons, which are composed of quarks.
That is the correct spelling of the plural noun "particles" (dust, or subatomic masses).
These masses cannot be measured directly; they are derived by calculation from other physical data.
They have different masses, electrical charge, dimensions, life time, spin etc.
