Process `I X (g) overset(3e^(-))(rarr)X^(3-) (g)`
Process II `X(g) overset(-3e^(-))(rarr)X^(3+)(g)`
  Which of the following is not changed during both the processes? 

Options

A. Total number of protons
B. Number of neutrons
C. Both (A) and (B)
D. Total number of electrons

Answer

To solve the question regarding the processes involving the element X, we need to analyze the changes that occur in each process.

### Step 1: Analyze Process I
In Process I, we have:
\[ I X (g) \overset{3e^{-}}{\rightarrow} X^{3-} (g) \]

Here, the element X gains 3 electrons, resulting in the formation of an ion with a charge of -3.

- **Change in Electrons**: The number of electrons increases by 3.
- **Change in Protons**: The number of protons remains unchanged.
- **Change in Neutrons**: The number of neutrons remains unchanged.

### Step 2: Analyze Process II
In Process II, we have:
\[ X(g) \overset{-3e^{-}}{\rightarrow} X^{3+} (g) \]

In this process, the element X loses 3 electrons, resulting in the formation of an ion with a charge of +3.

- **Change in Electrons**: The number of electrons decreases by 3.
- **Change in Protons**: The number of protons remains unchanged.
- **Change in Neutrons**: The number of neutrons remains unchanged.

### Step 3: Determine What Remains Unchanged
From the analysis of both processes, we can summarize the changes:
- **Total Number of Electrons**: Changes (increases in Process I and decreases in Process II).
- **Total Number of Protons**: Remains unchanged in both processes.
- **Total Number of Neutrons**: Remains unchanged in both processes.

### Conclusion
The quantities that do not change during both processes are:
- Total number of protons
- Total number of neutrons

Thus, the correct answer to the question is that the total number of protons and the total number of neutrons are not changed during both processes.

### Final Answer
The total number of protons and the total number of neutrons do not change during both processes.
