Atomic of the transition elements than those of the s-block elements because:A. there is increase in the nuclear charge along the period.B. orbital electrons are added to the penultimate d-subshell rather than to the outer shell of the atom.C. the shielding effect of d-electrons is small.D. All of these. |

Answer» Correct Answer - D The atomic radii of the transition metals lie in -between those of s- and p-block elements . In the begininh, the atomic radius decrease with the increase in nuclear charge (as atomic number increase), whereas the shielding effect of d-electrons is small and orbital electrons are added to the penultimate d-subshell rather than tot he outer shell of the atom. |
