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.

Atomic weight (not mass) of uranium is 238,02891.
Uranium is a radioactive element. It is in the f block. We use it for make energy.
the atomic radius of antimony is 159
Bismuth has an atomic radius of 156 picometers.
Fluorine has the smallest atomic radius, while Francium has the largest atomic radius.

The other word for atomic radius includes the Van der Waals radius, ionic radius, and covalent radius. The atomic radius refers to half the distance between the nuclei of identical neighboring atoms in the solid form of an element.
Fluorine has the smallest atomic radius, while Francium has the largest atomic radius.
