Detailed explanation-1: -We will use the covalent radius (Figure 6.31), which is defined as one-half the distance between the nuclei of two identical atoms when they are joined by a covalent bond (this measurement is possible because atoms within molecules still retain much of their atomic identity).

Detailed explanation-2: -Van Der Waal’s radius is one half of the distance between the nuclei of two non bonded adjacent atoms belonging to two neighboring molecules of an elements in the solid state.

Detailed explanation-3: -Van Der Waals Radius It is one the distance which is half the distance between the nuclei of two similar non-bonded isolated atoms or even two adjacent identical atoms belonging to two neighboring molecules of an element which are in the solid-state.
