1.	Find the number pair of ions which have same outermost E.C. Set I : (Ac^(3+),Th^(4+)), (Th^(3+), Pa^(4+)), Pa^(3+), U^(4+)), (U^(3+), Np^(4+)), (Np^(3+), Pu^(4+)), Pu^(3+), Am^(4+)), (Am^(3+), Cm^(4+)), (Cm^(3+), Bk^(4+)), (Bk^(3+), Cf^(4+)), (Cf^(3+), Es^(4+)), (Es^(3+), Fm^(4+)), (Fm^(3+), Md^(4+)), (Md^(3+), No^(4+)), (No^(3+), Lr^(4+)) Set II : (La^(2+), Ce^(3+)), (Ce^(2+), Pr^(3+)), (Pr^(2+), Nd^(3+)), (Nd^(2+), Pm^(3+)), (Pm^(2+), Sm^(3+)), (Sm^(2+), Eu^(3+)), (Eu^(2+), Gd^(3+)), (Gd^(2+), Tb^(3+)), (Tb^(2+), Dy^(3+)), (Dy^(2+), (Ho^(3+)), (Er^(2+), Tm^(3+)), (Tn^(2+), Yb^(3+)), (Yb^(2+), (Lu^(3+)) If the value of set I is 'x' and set II is 'y', then find \|x-y\|.
Answer» Solution :`[[LA^(2+) rarr 5d^(1)],[Ce^(3+) rarr 4F^(1)]],[[Gd^(2+) rarr 4f^(7)5d^(1)],[Th^(3+) rarr 4f^(8)]]` EXPECT these TWO pairs, all other pairs have same outermost E.C.
