Dear zahid,

The van der Waal's radius is the distance between two atom centers when the force required to move the atoms closer to each other becomes positive (i.e., repulsive). It is the effective radius of an atom, as atoms are somewhat compressible or polarizable due to the majority of their volume being electron orbital clouds. The vdW radius is also known as the "hard sphere" radius, that is, it gives the size of an atom when it acts like a hard sphere. Remember, though, that at the atomic scale the world is very different (i.e., a quantum mechanical world, not Newtonian). "Hard sphere" is an analogy to something at our scale and is not a true description of an atom.
