Question

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

The Van der Waals radius is equal to one half the distance between two unbonded atoms when the electrostatic forces between them are balanced.

it is half of the closest distance between two atoms that aren't bonded or within the same molecule.

Picometers (pm) is the unit used to report the value.
