Of the following transition metals, the maximum numbers of oxidation states are exhibited by:

1. Chromium (Z = 24)
2. Manganese (Z = 25)
3. Iron (Z = 26)
4. Titanium (Z = 22)

Correct answer: Manganese (Z = 25)

Solution

Manganese (Z = 25) exhibits the maximum number of oxidation states among the given options, ranging from +2 to +7, due to its ability to lose electrons from both 3d and 4s orbitals.
