The correct answer is: $\mathrm{Ni}, \mathrm{Zr}$
Mond's Process :
$\begin{array}{r}\mathrm{Ni}(\mathrm{s}) \text { (impure) }+4 \mathrm{CO} \stackrel{\Delta}{\longrightarrow} \mathrm{Ni}(\mathrm{CO})_4(\mathrm{~g}) \stackrel{\Delta}{\longrightarrow} \\ \mathrm{Ni}(\mathrm{s}) \text { (pure) }+4 \mathrm{CO}\end{array}$
Van Arkel Process :
$\mathrm{Zr}+2 \mathrm{I}_2 \stackrel{\Delta}{\longrightarrow} \mathrm{ZrI}_4 \stackrel{\Delta}{\longrightarrow} \mathrm{Zr}+2 \mathrm{I}_2$
