I now accept that atomic radi decreases left to right across a period thus the nobles gases being at the extrem right of each row should have the smallest atomic radi. Thanks am now cleared.

the thing about noble gases having a larger atomic radius is in our book too. infact, they claimed noble gases have almost twice the radius as the halogen before them. hat i think they mean is that it is that way when you take inter molecular (atomic distance) distance between them... but it still doesnt make sense because they clearly mentioned that the reason for their big size is inter-electron repulsion because there are just "too many" electrons in there and they dont like each others' company much.
can anyone plz tell me more on this?

Check out the various ways we refer to atomic radius under "Definitions" at
