Question

Toppr Admin · Accepted Answer

No- of unpaired d electrons in the given ions is as follow-Zn-x2212-1Fe2-x2212-4Ni-x2212-3Cu-x2212-0-xA0-So- Fe2- has maximum number of unpaired electrons among the given elements-

Which of the following has more unpaired d electrons?

Fe $^{2 +}$
Zn $^{+}$
Ni $^{+}$
Cu $^{+}$

No. of unpaired d electrons in the given ions is as follow:
$Z n^{+} - 1$
$F e^{2 +} - 4$
$N i^{+} - 3$
$C u^{+} - 0$
So, $F e^{2 +}$ has maximum number of unpaired electrons among the given elements.

Which of the following has more unpaired d electrons? Fe2+Zn+Ni+Cu+

No. of unpaired d electrons in the given ions is as follow:Zn+−1Fe2+−4Ni+−3Cu+−0 So, Fe2+ has maximum number of unpaired electrons among the given elements.
