Which elements gives maximum balanced oxide

Options

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

Explanation

To determine which element gives the maximum balanced oxide, we need to analyze the oxidation states of various elements and their corresponding oxides. Here’s a step-by-step breakdown of the solution:

### Step 1: Understand Oxidation States
- Oxidation state refers to the degree of oxidation of an atom in a compound. The higher the oxidation state, the more oxygen atoms can be combined with the element to form oxides.

**Hint:** Remember that the oxidation state indicates how many electrons an element can lose or share during a reaction.

### Step 2: Identify Relevant Elements
- We will consider transition metals, as they often form multiple oxides with varying oxidation states. Key elements to consider include:
- Vanadium (V)
- Chromium (Cr)
- Manganese (Mn)
- Iron (Fe)

**Hint:** Focus on transition metals, as they are known for their variable oxidation states.

### Step 3: Determine Maximum Oxidation States
- Check the maximum oxidation states for the elements:
- **Vanadium (V)**: Maximum oxidation state of +5
- **Chromium (Cr)**: Maximum oxidation state of +6
- **Manganese (Mn)**: Maximum oxidation state of +7
- **Iron (Fe)**: Maximum oxidation state of +3

**Hint:** Look for the element with the highest oxidation state, as it will likely form the most oxides.

### Step 4: Analyze Oxides Formed
- Now, let’s look at the oxides formed by these elements:
- **Vanadium**: V2O5
- **Chromium**: CrO3
- **Manganese**: MnO, MnO2, Mn2O3, Mn3O4, MnO4 (MnO7)
- **Iron**: FeO, Fe2O3

**Hint:** Count the different types of oxides formed by each element to see which one has the most variety.

### Step 5: Conclusion
- Among these elements, **Manganese (Mn)** has the highest oxidation state of +7 and forms several oxides, including MnO, MnO2, Mn2O3, Mn3O4, and Mn2O7. Therefore, it gives the maximum balanced oxide.

**Final Answer:** The element that gives the maximum balanced oxide is **Manganese (Mn)**.
