Atomic radii: The atomic radii of an atom depends on its position in the periodic table.
We can never determine the atomic radius of an atom because there is never a zero probability of finding an electron, and thus never a distinct boundary to the atom.
All that we can measure is the distance between two nuclei (internuclear distance).
