Yes. There are other measures for ions (ionic radius) and free atoms(atomic radius) and covalent radius. Metallic, ionic and covalent are based on measurements of distances in crystals or covelnt bond lengths, atomic radius is based more on calcuation than observation.
The covalent radius of argon is 106 +/- 10 picometers.
The element with the longest covalent radius among Li, B, N, and F is Li. This is because as you move down a group in the periodic table, the atomic radius increases due to the addition of new electron shells. The covalent radius generally follows this trend.
noble gases have larger radius than cations.
