Vedclass · Answer

(C) substance is paramagnetic if it contains at least one unpaired electron. Let us analyze the electronic configurations of the ions in option $C$: $Ti$ $(Z=22)$: $[Ar] 4s^{2} 3d^{2}$. $Ti^{2+}$: $[Ar] 3d^{2}$ (contains $2$ unpaired electrons). $Cu$ $(Z=29)$: $[Ar] 4s^{1} 3d^{10}$. $Cu^{2+}$: $[Ar] 3d^{9}$ (contains $1$ unpaired electron). $Mn$ $(Z=25)$: $[Ar] 4s^{2} 3d^{5}$. $Mn^{3+}$: $[Ar] 3d^{4}$ (contains $4$ unpaired electrons). Since all these ions contain unpaired electrons,they are paramagnetic.

Identify the set of paramagnetic ions among the following.
