Ethylene diamine tetra acetate ion (EDTA) is a polydentate ligand, it bonds to central metal atom through:
Correct answer: D. Six of its atoms
- A. Two of its atoms
- B. Three of its atoms
- C. Four of its atoms
- D. Six of its atoms
Explanation
When this ion bonds to a metal atom, the two N atoms, and four of the O atoms, are used. In this complex, a single EDTA4- ion forms 6 bonds to the Fe atom (i.e., 2 Fe-N bonds and 4 Fe-O bonds). The coordination number of 6 results in an octahedral structure.

About Electronic Structure of d-Block Elements
The electronic structure of d-block elements covers the filling of the (n-1)d and ns orbitals, general electronic configurations, and the exceptions shown by chromium and copper. It explains how partially filled d orbitals produce variable oxidation states, coloured ions, magnetic behaviour and complex formation, while distinguishing transition elements from elements with completely filled d subshells.
