Final answer:
The letter representing the range of oxidation states for manganese can be Mn(I) to Mn(VII), reflecting its diverse electron configurations which make it a significant element in various scientific fields.
Step-by-step explanation:
The letter that refers to the range of manganese can either be Mn(I) through Mn(VII). This range indicates the various oxidation states that manganese can exist in. For instance, the most stable ion for manganese in terms of oxidation state is Mn(II), but it can also exist as Mn(0) in the form of solid manganese (Mn(s)), as Mn (III) in Mn3O4, as Mn(IV) in manganese dioxide (MnO2), and up to Mn(VII) in the permanganate ion (MnO4-). Manganese exhibits a wide range of oxidation states because of its ability to lose a varying number of electrons from its d-orbital. This characteristic makes manganese an element of considerable interest in chemical analysis, biochemistry, and metallurgy.
