The Van der Waals radii of O,N,Cl,F and Ne increases in the order?
Van der Waals radius decreases along a period from left to right due to increase in nuclear charge and then increases at noble gasses.
Chlorine being the element from the third period and rest from the second period has the largest size.
The van der Waal's radii for the afore mentioned elements are:
N- 155 pm
O- 152 pm
F- 147 pm
Ne- 154 pm
Cl- 175 pm
