Match the increasing orders given in column I with the property given

1.	Match the increasing orders given in column I with the property given in column II {:("Column-I","Column-II"),((A)Na^+ ltF^(-) ltO^(2-)ltN^(3-),(p)"Electronegativity"),((B)Li^(+)ltNa^(+)ltK^(+)ltRb^(+)ltCs^(+),(q)"Nuclear charge"),((C )"OltSltFltCl",(r)"Size"),((D)Cl^(-)ltK^(+)ltCa^(2+)ltSc^(2+),(s)"Electron affinity"),(,(t)"Ionisation energy"):}
Answer» Solution :(A)For isoelectronic species, the ionic size decrease with INCREASE in NUCLEAR charge (B)Number of atomic shells increases, ionic size increases. (C )Correct order,as Cl has less inter electronic repulsions than F due to bigger size of 3p-subshell (D)Oxidation STATE increases, the electronegativity increases.For isoelectronic species IONISATION energy and electron affinity increases with increasing nuclear charge.
