All the above

Vedclass · Answer

(D) The atomic radii of transition elements in a series remain almost constant because the increase in nuclear charge is balanced by the increase in the screening effect provided by the $d$-electrons. As we move from $Cr$ to $Cu$,the nuclear charge increases,but the added electrons enter the inner $(n-1)d$ orbitals,which provide effective shielding. This shielding effect counteracts the increase in nuclear charge,resulting in nearly constant atomic radii. Therefore,the correct answer is $(D)$.

The atomic radii from $Cr$ to $Cu$ are almost identical because of:
