Question

Define vanderwaal 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

Answer:

The van der walls radius is equal to the half of the distance between the two unbonded atoms,

When the electrostatic force between them are balanced.

In other words, it is half of the closest distance between two atoms that are not bounded or within the same molecule,
