Van der Waals radius
It Is defined as one half the distance between the nuclei of two identical non bonded isolated atoms or two adjacent identical atoms belonging to two
neighbouring molecules of an element in the solid
state.
The magnitude of the van der Waal radius depends
upon the packing of the atoms when the element is
in the solid state.
For Example:The inter nuclear distance between two
adjacent chlorine atoms of the two neighbouring
molecules in the solid state is 360 pm. The van der
waals radius of chlorine atom is 180 pm.
The inter nuclear distance between two adjacent hydrogen atoms of the two neighbouring molecules
in the solid state 240 pm. The van der Waals radius is
120 pm
