Solution
Correct Answer:
+7
Manganese (Mn) has the electronic configuration [Ar]3d54s2.
- It has the maximum number of unpaired electrons in the 3d series. It can lose or share all 7 valence electrons (5 from 3d and 2 from 4s).
- Maximum State: +7, which is seen in the Permanganate ion (MnO4−).
- This is the highest oxidation state for any element in the first transition (3d) series.
This easy difficulty chemistry question is from the chapter d- and f-block elements, covering the topic of oxidation states. It appeared in the 2025 exam.
