If EAN of metal is 36 in

$\left[\mathrm{M}(\mathrm{CO}{)}_2\left(\sigma -{\mathrm{C}}_5{\mathrm{H}}_5\right)\left(\pi -{\mathrm{C}}_5{\mathrm{H}}_5\right)\right]$

Find the atomic number of metal M

An element's typical metallic atom is one that is bright and exhibits strong electrical and thermal conductivity. The atomic number of metals M is 26.

$\mathrm{EAN}\Rightarrow Z-\left(2\right)+2\times 2+1\times 2+3\times 2=36$

$Z\Rightarrow 26$

Hence correct answer is 0026.
