D. 44

Answer

To find the number of electrons in 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 (C)
- Oxygen (O)

2. **Determine the atomic number of Carbon**:
- The atomic number of carbon is 6. This means that a neutral carbon atom has 6 electrons.

3. **Determine the atomic number of Oxygen**:
- The atomic number of oxygen is 8. This means that a neutral oxygen atom has 8 electrons.

4. **Count the number of oxygen atoms in CO₂**:
- There are 2 oxygen atoms in carbon dioxide (CO₂).

5. **Calculate the total number of electrons contributed by oxygen**:
- Since there are 2 oxygen atoms, the total number of electrons from oxygen is:
\[ 2 \times 8 = 16 \text{ electrons} \]

6. **Calculate the total number of electrons in CO₂**:
- Now, add the number of electrons from carbon and the total number of electrons from oxygen:
\[ \text{Total electrons} = \text{Electrons from Carbon} + \text{Electrons from Oxygen} \]
\[ \text{Total electrons} = 6 + 16 = 22 \text{ electrons} \]

### Final Answer:
The total number of electrons in carbon dioxide (CO₂) is **22**.
