Which has a greater mass protons or neutrons?
The mass of a neutron is slightly greater than the mass of a proton, which is 1 atomic mass unit (amu). (An atomic mass unit equals about 1.67×10−27 kilograms.) A neutron also has about the same diameter as a proton, or 1.7×10−15 meters.

Does proton have the greatest mass?
A neutron has a slightly larger mass than the proton. These are often given in terms of the atomic mass unit, where one atomic mass unit is defined as the 1/12th the mass of the carbon-12 atom. Hence, neutrons have the greatest mass.
