The correct Answer is:
To determine which transition metal exhibits the maximum number of oxidation states among chromium (Z=24), manganese (Z=25), iron (Z=26), and titanium (Z=22), we can analyze the electron configurations and the possible oxidation states for each metal. ### Step-by-Step Solution: 1. **Identify Electron Configurations:** - **Chromium (Cr, Z=24):** The electron configuration is [Ar] 3d⁵ 4s¹. - **Manganese (Mn, Z=25):** The electron configuration is [Ar] 3d⁵ 4s². - **Iron (Fe, Z=26):** The electron configuration is [Ar] 3d⁶ 4s². - **Titanium (Ti, Z=22):** The electron configuration is [Ar] 3d² 4s². 2. **Determine Possible Oxidation States:** - **Chromium:** - Possible oxidation states: +2, +3, +4, +5, +6 (due to the loss of 4s and 3d electrons). - Maximum oxidation state: +6. - **Manganese:** - Possible oxidation states: +2, +3, +4, +5, +6, +7 (due to the loss of 4s and 3d electrons). - Maximum oxidation state: +7. - **Iron:** - Possible oxidation states: +2, +3 (due to the loss of 4s and 3d electrons). - Maximum oxidation state: +3. - **Titanium:** - Possible oxidation states: +2, +3, +4 (due to the loss of 4s and 3d electrons). - Maximum oxidation state: +4. 3. **Compare Maximum Oxidation States:** - Chromium: +6 - Manganese: +7 - Iron: +3 - Titanium: +4 4. **Conclusion:** - The transition metal that exhibits the maximum number of oxidation states is **manganese (Mn)** with a maximum oxidation state of +7. ### Final Answer: The maximum number of oxidation states are exhibited by **manganese (Z=25)**.
