$A$ trend common to both groups $I$ and $VII$ elements in the periodic table as atomic number increases is

If the interionic distance between $Na^{+}$ and $F^{-}$ ions is $2.31 \ \mathring{A}$,then the radii of $Na^{+}$ and $F^{-}$ are:

If four different elements $A, B, C$ and $D$ have electronic configurations as $A = [Ne] 3s^2 3p^4$,$B = [Ne] 3s^2 3p^5$,$C = [Ar] 3d^{10} 4s^2 4p^4$ and $D = [Ar] 3d^{10} 4s^2 4p^5$,identify the element with the largest atomic radius.

What is the correct order of radii for $F, F^-, O,$ and $O^{2-}$?

Which group elements have the smallest atomic radii in their respective periods?

Atomic radii of fluorine and neon in $\mathring{A}$ units are respectively given by
