The total number of electrons in one molecular of carbon dioxide is

Options

A. 22
B. 44
C. 66
D. 88

Explanation

To find the total number of electrons in one molecule of carbon dioxide (CO₂), we need to consider the number of electrons contributed by each atom in the molecule.

### Step-by-Step Solution:

1. **Identify the atoms in CO₂**:
Carbon dioxide consists of one carbon atom and two oxygen atoms.

2. **Find the atomic number of carbon**:
The atomic number of carbon (C) is 6. This means that a neutral carbon atom has 6 electrons.

3. **Find the atomic number of oxygen**:
The atomic number of oxygen (O) is 8. Therefore, each neutral oxygen atom has 8 electrons.

4. **Calculate the total number of electrons from the oxygen atoms**:
Since there are two oxygen atoms in carbon dioxide, the total number of electrons from the oxygen atoms is:
\[ 2 \times 8 = 16 \text{ electrons} \]

5. **Add the number of electrons from carbon and oxygen**:
Now, we add the number of electrons from the carbon atom and the two oxygen atoms:
\[ 6 \text{ (from carbon)} + 16 \text{ (from oxygen)} = 22 \text{ electrons} \]

6. **Conclusion**:
Therefore, the total number of electrons in one molecule of carbon dioxide (CO₂) is 22.

### Final Answer:
The total number of electrons in one molecule of carbon dioxide is **22**.
