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

Hey

The van der Waals radius, rw, of an atom is the radius of an imaginary hard sphere representing the distance of closest approach for another atom. It is named after Johannes Diderik van der Waals, winner of the 1910 Nobel Prize in Physics, as he was the first to recognise that atoms were not simply points and to demonstrate the physical consequences of their size through the van der Waals equation of state.
