JEE Main 2024 — 27 January, Shift 2 — Question 62

Choose the correct option having all the elements with $\mathrm{d}^{10}$ electronic configuration from the following:

Option A:
${ }^{27} \mathrm{Co},{ }^{28} \mathrm{Ni},{ }^{26} \mathrm{Fe},{ }^{24} \mathrm{Cr}$
Option B:
${ }^{29} \mathrm{Cu},{ }^{30} \mathrm{Zn},{ }^{48} \mathrm{Cd},{ }^{47} \mathrm{Ag}$
Correct
Option C:
${ }^{46} \mathrm{Pd},{ }^{28} \mathrm{Ni},{ }^{26} \mathrm{Fe},{ }^{24} \mathrm{Cr}$
Option D:
0 ${ }^{28} \mathrm{Ni},{ }^{24} \mathrm{Cr},{ }^{26} \mathrm{Fe},{ }^{29} \mathrm{Cu}$

$[\mathrm{Cr}]=[\mathrm{Ar}] 4 \mathrm{~s}^{1} 3 \mathrm{~d}^{5}$

$[\mathrm{Cd}]=[\mathrm{Kr}] 5 \mathrm{~s}^{2} 4 \mathrm{~d}^{10}$

$[\mathrm{Cu}]=[\mathrm{Ar}] 4 \mathrm{~s}^{1} 3 \mathrm{~d}^{10}$

$[\mathrm{Ag}]=[\mathrm{Kr}] 5 \mathrm{~s}^{1} 4 \mathrm{~d}^{10}$

$[\mathrm{Zn}]=[\mathrm{Ar}] 4 \mathrm{~s}^{2} 3 \mathrm{~d}^{10}$
