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» Correct Answer - A-r ; B-q,r ; C-s ; D-p,q,s,t (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. |
