Which has same charge on central metal atom as the co-ordination sphere
Correct answer: C. [Cu(NH3)4]SO4
- A. K4 [Fe(CN)6]
- B. [Co(NO2)3(NH3)3]
- C. [Cu(NH3)4]SO4
- D. .[MnCl4]-2
Explanation
In C option central metal atom and coordination sphere has same charge [Cu+2(NH3)04]+2SO4-2 Here the coordination sphere has a +2 sign and the central metal atom i.e Cu also has +2 charge because NH3 is a neutral ligand. Thus, this option is incorrect.

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.
