Define Van der waal radius

Answer 1

$\underline{\underline{\Huge\mathfrak{Answer-: }}}$

★$\bold{Van\: der\: Waal's\: radius}$

●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 Waals radii depends upon the packing of the atoms when the element is in the solid state.

Answer 2

van der Waals radius is defined as half of the internuclear separation of two non-bonded atoms of the same element on their closest possible approach and is denoted rv. ... In addition to not being covalently bonded, the atoms must also not be of the same molecule.
