1If F has greater size than Ne then we know F- has greater size than F so F- is greater than Ne so it should be true,the statement??
F- has has greater size than Ne
True/false
I think its true but my book says Ne

19its false.....actually, F is greater in size than Ne ...not F-...

1bt we always take size of noble gas atoms greater than other members of the period
11hey these are isoelectronic species..for this there is a golden rule---
z increases,,,size decreases...
another size series is --
N3- > O2- > F- > Na+ > Mg2+ > Al3+
I think ans given in the book is wrong..ur reasoning in post 3 is also right.
1ya i agree vid ronald..............................noble gas size is gr88 er than F not F-
23F- has to be bigger in size than F and thus Ne ...
bcz of the repulsion of the electrons ...
for eg: H- is very very big than H, and my prof even claimed that H- is almost the size of an Iodine atom ..... is it really ..or was he just being hyper
19what is "typo" ? anyways, i a bit wrong here....actually i was confused between the relative sizes of cations and anions ! .....
1Its simple guys! F- and Ne are isoelectronic. now the effective nuclear charge in F- is less than that in Ne(as the number of protons in F- is less than that in Ne),thus obviously implying that F- would have a greater size than Ne.
