Coordination number of Fe in [Fe(CN)6]-4 ion is:
Correct answer: C. 6
- A. 4
- B. 2
- C. 6
- D. -4
Explanation
The coordination number refers to the number of atoms or ions bonded directly to the central atom in a complex ion or molecule. In [Fe(CN)6]^-4, the central atom is Fe (iron), which is bonded to six cyanide ions (CN^-). Therefore, the coordination number of Fe in [Fe(CN)6]^-4 is 6.

About Transition Elements
Transition elements are identified by their partially filled d subshells in atoms or common ions. The topic covers the electronic structure of d-block elements, including the filling order of 4s and 3d orbitals, variable oxidation states and the distinction between transition elements and elements with completely filled d subshells.
