Thesize ofisoelectronicspecies-F^(-) ,Neand Na^(+)isaffected by ( a)nu

1.	Thesize ofisoelectronicspecies-F^(-) ,Neand Na^(+)isaffected by ( a)nuclear charge ( Z)( b)valenceprincipalquantumnumber (n) (c ) electron- electron interactionin theoutherorbital ( d) noneof thefactorsbacausetheir size is thesame .
Answer» Solution :The SIZEOF the isoelectronic ionsdependsupon thenuclear CHARGE (Z) . As thenuclearchargeincreases the sizedecreases . Forexample `F^(-)(+9) gt Ne + (+10) gt Na^(+) (+11)`. Thereforestatement (a) iscorrect while all otherstatementare wrong .
