Q35 (CISF/2018) Science & Technology › Basic Science (Physics, Chemistry, Biology)

Which one of the following elements has the oxidation state as +7 ?

Explanation

Manganese (Mn) is a transition metal that exhibits a wide range of oxidation states, from -3 to +7, due to the availability of electrons in both its 3d and 4s subshells. The +7 oxidation state is the highest for manganese and is found in powerful oxidizing agents such as the permanganate ion (MnO4-), as seen in Potassium Permanganate (KMnO4).

  • Nitrogen (N) and Phosphorus (P) belong to Group 15; their maximum oxidation state is generally +5 (e.g., in HNO3 and H3PO4).
  • Magnesium (Mg) is an alkaline earth metal (Group 2) and almost exclusively exhibits an oxidation state of +2 in its compounds.
