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 can follow these steps:

### Step-by-Step Solution:

1. **Identify the Composition of Carbon Dioxide:**
- Carbon dioxide (CO₂) consists of one carbon atom and two oxygen atoms.

2. **Determine the Number of Electrons in Carbon:**
- The atomic number of carbon (C) is 6. This means that a neutral carbon atom has 6 electrons.

3. **Determine the Number of Electrons in Oxygen:**
- The atomic number of oxygen (O) is 8. Therefore, each neutral oxygen atom has 8 electrons.

4. **Calculate the Total Electrons from Oxygen:**
- Since there are two oxygen atoms in carbon dioxide, we multiply the number of electrons in one oxygen atom by 2:
\[ 2 \text{ (O)} \times 8 \text{ electrons} = 16 \text{ electrons} \]

5. **Calculate the Total Number of Electrons in CO₂:**
- Now, we add the number of electrons from carbon and the total number of electrons from the two oxygen atoms:
\[ 6 \text{ (from C)} + 16 \text{ (from 2 O)} = 22 \text{ electrons} \]

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