Name the metal

M

which is extracted on the basis of following reactions,

4M + 8\mathrm{C}{\mathrm{N}^ - } + 2{\mathrm{H}_2}\mathrm{O} + {\mathrm{O}_2} \to 4{\left[ {M{{\left( {\mathrm{CN}} \right)}_2}} \right]^ - } + 4\mathrm{O}{\mathrm{H}^ - }

2{\left[ {M{{\left( {\mathrm{CN}} \right)}_2}} \right]^ - } + \mathrm{Zn} \to {\left[ {\mathrm{Zn}{{\left( {\mathrm{CN}} \right)}_4}} \right]^{2 - }} + 2M
