Which of the following compounds contains a transition metal with the same number of d-electrons as Ti ⁴⁺ ?

Step-by-step solution

The atomic number of Ti is 22, and its electronic configuration is [ Ar ] 4 s ^2 3 d ^2 . In the Ti ⁴⁺ ion, the configuration is [ Ar ] 3 d ^0 , meaning it has 0 d-electrons. Now, let us determine the oxidation state and d-electron count for the transition metal in each given compound: In K ₂ MnO ₄ , the oxidation state of Mn is +6. The configuration of Mn ⁶⁺ is [ Ar ] 3 d ^1 (1 d-electron). In VOSO ₄ , the oxidation state of V is +4. The configuration of V ⁴⁺ is [ Ar ] 3 d ^1 (1 d-electron). In Fe ₂ O ₃ , the oxid
