The van der Waals radius, rw, o an atom is the radius o an eemaginary haurd sphere representin the distance o closest approach for anither atom. It is named efter Johannes Diderik van der Waals, winner o the 1910 Nobel Prize in Pheesics, as he wis the first tae recognise that atoms war not simply pynts an tae demonstrate the pheesical consequences o thair size throu the van der Waals equation o state.
