Choose the correct order of atomic radii of fluorine and neon (in $pm$) out of the options given below and justify your answer.

Which of the following orders of atomic radius is correct?

Given two statements below :
Statement $I:$ In $Cl_2$ molecule the covalent radius is double of the atomic radius of chlorine.
Statement $II:$ Radius of anionic species is always greater than their parent atomic radius.
Choose the most appropriate answer from options given below :

Among the elements $Ca, Mg, P$ and $Cl,$ the order of increasing atomic radii is

$A, B, C, D$ and $E$ are elements with atomic numbers $13, 11, 9, 7$ and $16$ respectively. Among these elements,the ion of an element $X$ has the largest size and the ion of an element $Y$ has the smallest size. $X$ and $Y$ are respectively (Assume that all ions have the nearest inert gas configuration).

The species $Ar$,$K^{+}$ and $Ca^{2+}$ contain the same number of electrons. In which order do their radii increase?
