It may sound silly, but neutrons are all pretty much alike. And they're very close in size to a proton. If you're looking for some numbers, try these: Radius: 1.1 x 10-15 m Mass: 1.6749×10-27 kg Note that there is variability in the mass. And yes, we already said they were all alike. Thing is, when neutrons are in a nucleus, they have to drop a bit of mass to make a contribution to what is called binding energy or nuclear glue. A neutron has a bit less mass in a nucleus than a free neutron. But a free neutron is unstable and has a half life of a bit less than 15 minutes. Fair trade? Note that you could "touch up" numbers a bit, but we're talking about something so small that the quantification you have before you will work for just anything in the undergraduate course list.
