The oxidation state of `M^(3+)` after removing three elelctrons is

Options

A. Zero
B. `+3`
C. `+6`
D. `-6`

Explanation

To find the oxidation state of \( M^{3+} \) after removing three electrons, we can follow these steps:

### Step 1: Understand the Initial State
The species \( M^{3+} \) indicates that the element \( M \) has a charge of +3. This means that it has lost three electrons compared to its neutral state.

### Step 2: Determine the Charge After Electron Removal
When we talk about removing electrons, we are essentially increasing the positive charge of the species. If \( M^{3+} \) has already lost three electrons, removing three more electrons would increase its positive charge.

### Step 3: Calculate the New Oxidation State
Starting from \( M^{3+} \):
- Initial charge: +3
- After removing 3 electrons, the charge becomes:
\[ +3 + 3 = +6 \]
Thus, the new oxidation state of \( M \) after removing three electrons is +6.

### Final Answer
The oxidation state of \( M^{3+} \) after removing three electrons is \( +6 \).
