WebAtomic Radius. Unlike a ball, an atom does not have a fixed radius. The radius of an atom can only be found by measuring the distance between the nuclei of two touching atoms, and then halving that distance. As you can see from the diagrams, the same atom could be found to have a different radius depending on what was around it. http://www.elch.chem.msu.ru/rus/spec/Vvedenie_v_spetsialnost_3/Hydrated_ions.pdf how many ridings are in the gtaWebAll values of radii are given in picometres (pm).
