The correct Answer is:
To determine the transition element with the highest oxidation state and its corresponding group, we can follow these steps: ### Step 1: Identify the Transition Elements Transition elements are defined as the d-block elements in the periodic table, which include groups 3 to 12. ### Step 2: Determine the Highest Oxidation State The highest oxidation states for transition metals are typically +7 or +8. We need to identify which transition metals can achieve these oxidation states. ### Step 3: Examine Specific Transition Elements 1. **Ruthenium (Ru)**: - Atomic Number: 44 - Electronic Configuration: [Kr] 4d^7 5s^2 - Ruthenium can exhibit a maximum oxidation state of +8. 2. **Osmium (Os)**: - Atomic Number: 76 - Electronic Configuration: [Xe] 4f^14 5d^6 6s^2 - Osmium can also exhibit a maximum oxidation state of +8. ### Step 4: Identify the Group of These Elements Both Ruthenium and Osmium belong to **Group 8** of the periodic table. ### Conclusion The transition elements that have the highest oxidation state (+8) are Ruthenium (Ru) and Osmium (Os), and they belong to **Group 8**. ---
