$\mathrm{Z}=29\left(\mathrm{Cu}\right)$

${\mathrm{Cu}}^{2+}$ form ${\left[\mathrm{Cu}{\left({\mathrm{H}}_2\mathrm{O}\right)}_4\right]}^{2+}$ complex ion with ${\mathrm{H}}_2\mathrm{O}$

${\left[\mathrm{Cu}{\left({\mathrm{H}}_2\mathrm{O}\right)}_4\right]}^{2+}\Rightarrow {\mathrm{Cu}}^{2+}\left[\mathrm{Ar}\right]3 {\mathrm{d}}^9,{\mathrm{H}}_2\mathrm{O}\to \mathrm{WFL}$

number of unpaired ${\mathrm{e}}^{-}=1$

$\mu =\sqrt{1\left(1+2\right)}\mathrm{B}.\mathrm{M}$

$\mu =\sqrt{3}\Rightarrow 1.73 \mathrm{B}.\mathrm{M}.\Rightarrow$round off ans. $\Rightarrow 2$
