InterviewSolution

1.	The atomic radius of elements of which of the following series would be nearly the sameA. Na K Rb CsB. Li Be B CC. Fe Co Ni CuD. F Cl Br l
Answer» Correct Answer - C `Fe, Co, Ni, Cu. Due to shielding of d-electrons, the effect of increased nuclear charge due to increase in atomic no. neutralised. Consequently atomic radius remains almost unchanged after chromium.
