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.

Variation of Atomic Radius in the Periodic Table Variation in a Period: Along a period, the atomic radii of the elements generally decreases from left to right. Variation in a group: The atomic radii of the elements in every group of the periodic table increases as we move downwards.
means reference Ka data is wrong
which book is this??
Pradeeps
ncert Ka data hi follow krna hmesha sir
yes, always.
pradeeps is not reference book.. it is only guide book. I've checked it in many books and found that NCERT is absolutely correct
