Time management is very much important in IIT JAM. The eduncle test series for IIT JAM Mathematical Statistics helped me a lot in this portion. I am very thankful to the test series I bought from eduncle.

Absolutely you are right. Na+ ionic radii is greater than that of li+ it has higher no. of shells. Effective nuclear charge is the no. of proton that increases as we go down but it can,t compensate the increase in no. shell. But across the period as eletron are added in same shell so nuclear charge is dominant and it attracts the outer shell and radii deecreas.
