The maximum oxidation state in 3d series elements is shown by

Options

A. Cu
B. V
C. Mn
D. Fe

Answer

To determine which element in the 3d series shows the maximum oxidation state, we can follow these steps:

### Step 1: Identify the 3d Series Elements
The 3d series elements are the transition metals from Scandium (Sc, atomic number 21) to Zinc (Zn, atomic number 30). The elements in this series are:
- Scandium (Sc)
- Titanium (Ti)
- Vanadium (V)
- Chromium (Cr)
- Manganese (Mn)
- Iron (Fe)
- Cobalt (Co)
- Nickel (Ni)
- Copper (Cu)
- Zinc (Zn)

### Step 2: Determine the Oxidation States of Each Element
Each of these elements can exhibit various oxidation states. Here are the maximum oxidation states for some of the key elements:
- Scandium (Sc): +3
- Titanium (Ti): +4
- Vanadium (V): +5
- Chromium (Cr): +6
- Manganese (Mn): +7
- Iron (Fe): +6
- Cobalt (Co): +3
- Nickel (Ni): +2
- Copper (Cu): +2
- Zinc (Zn): +2

### Step 3: Identify the Maximum Oxidation State
From the list above, we can see that:
- Manganese (Mn) has a maximum oxidation state of +7.
- Chromium (Cr) has a maximum oxidation state of +6.
- Vanadium (V) has a maximum oxidation state of +5.
- All other elements have lower maximum oxidation states.

### Step 4: Conclusion
The element in the 3d series that shows the maximum oxidation state is Manganese (Mn), with an oxidation state of +7.

### Final Answer
The maximum oxidation state in the 3d series elements is shown by Manganese (Mn).
