Question

In group 1 of the periodic table three elements X Y Z have ionic radii 1.33A 0.95A. 0.60A respectively. Giving a reason arrange them in the order of increasing atomic numbers in the group

Answer 1

X( largest atomic number ) then Y and then Z ( smallest atomic number )

going down the atomic size increases as new shell is introduced every time we move down to new period.

hope it helps.
Mark it as brainliest

Answer 2

Explanation:

Z < Y < X

Because . the element having highest atomic radius will have highest number ... in other words as we go down the the number of atoms increase , increasing atomic number and radius....

Thank you
