The oxidation number of central metal atom in [Ni(CO)4 ] is
Correct answer: A. 0
- A. 0
- B. 2
- C. 4
- D. 6
Explanation
CO is a neutral monodentate ligand. The charge on the overall complex is zero. Let the oxidation state of Ni be x x +4(0) =0 x =0 The oxidation state of Ni =0

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.
