 One definition is half the shortest internuclear distance found

 For non-metallic elements, the
 covalent radius is often used
 as the atomic radius. This is half
 the internuclear distance
 between two identical atoms in
 a single covalent bond.

 For non-bonded adjacent atoms (e.g. in a covalent crystal of
 a non-metallic element), the van der Waals radius is used as
 a value for atomic radius. This is half the shortest internuclear
 distance between two similar non-bonded atoms.

 For metallic elements, the metallic radius is often used as
 the atomic radius. This is half the shortest internuclear
 distance between two adjacent atoms in a metallic bond.
