(A) An ion has zero magnetic moment if it has no unpaired electrons (diamagnetic).$V^{2+} = [Ar] 3d^3$ ($3$ unpaired electrons)$Zn^{2+} = [Ar] 3d^{10}$ ($0$ unpaired electrons)$Cu^{2+} = [Ar] 3d^9$ ($1$ unpaired electron)$Fe^{2+} = [Ar] 3d^6$ ($4$ unpaired electrons)$Fe^{3+} = [Ar] 3d^5$ ($5$ unpaired electrons)$Ti^{3+} = [Ar] 3d^1$ ($1$ unpaired electron)$Sc^{3+} = [Ar] 3d^0$ ($0$ unpaired electrons)$Ti^{4+} = [Ar] 3d^0$ ($0$ unpaired electrons)$Ni^{3+} = [Ar] 3d^7$ ($3$ unpaired electrons)$Co^{3+} = [Ar] 3d^6$ ($4$ unpaired electrons)$Cu^{+} = [Ar] 3d^{10}$ ($0$ unpaired electrons)The ions with zero magnetic moment are $Zn^{2+}$, $Sc^{3+}$, $Ti^{4+}$, and $Cu^+$.There are $4$ such ions.

Observe the following ions: $V^{2+}, Zn^{2+}, Cu^{2+}, Fe^{2+}, Fe^{3+}, Ti^{3+}, Sc^{3+}, Ti^{4+}, Ni^{3+}, Co^{3+}, Cu^+$. How many ions in the above list have zero magnetic moment?
