Question

Define Van der waals 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. Atoms must be (1) non-bonded, (2) the same element, and (3) not form different regions of same molecule.
