Match the following

LIST - 1	LIST - 2
A) $\mathrm{Pd}$	1) $3d^8$
B) ${\mathrm{Cu}}^{+}$	2) $3d^5$
C) ${\mathrm{Ni}}^{2+}$	3) $4d^{10}$
D) $\mathrm{Cr}$	4) $3d^{10}$
	5) $3d^9$

The element $\mathrm{Pd}$ has the electronic configuration $4{\mathrm{d}}^{10}$

${\mathrm{Cu}}^{+}$ has the electronic configuration $3{\mathrm{d}}^{10}$

${\mathrm{Ni}}^{2+}$ has the electronic configuration $3{\mathrm{d}}^8$

$\mathrm{Cr}$ has the electronic configuration $3{\mathrm{d}}^5$

Therefore Option C is the correct answer.
