If EAN of central metal ion $X^{2+}$ in a non-chelating complex is 34 and atomic number of X is 28. Find out the number of monodentate ligands in complex.

A metal complex's total number of electrons orbiting a metal atom's nucleus is represented by the EAN number. If EAN of central metal ion $X^{2+}$ in a non-chelating complex is 34 and atomic number of X is 28. The number of monodentate ligands in complex is 4.

$\begin{array}{l}28-2+2\times x=34\\ \Rightarrow x=4\end{array}$

Hence correct answer is 0004.
