Why is Krypton larger in size than bromine,even if atomic radius decreases while going from left to right across a period?

In case of Krypton being and inert gas it do not make any Bond and remains as as a single molecule due to this we calculate the Van der waal’s radius in case of these . Which is always larger as compared to other elements.

But in case of bromine we calculate the ionic radius or covalent radius which is smaller as compared to the Van der waal’s radius.
