Sure, let’s go through a step-by-step solution to determine whether the proposed Lewis structure is reasonable.
### Given Information
We are analyzing a Lewis structure with a Carbon (C) atom and two Oxygen (O) atoms. We need to verify the number of valence electrons in the proposed structure.
### Step-by-Step Solution
1. Identify the valence electrons for each element:
- Carbon (C): Carbon is in Group 14 of the periodic table, so it has 4 valence electrons.
- Oxygen (O): Oxygen is in Group 16 of the periodic table, so each oxygen atom has 6 valence electrons.
2. Calculate the total number of valence electrons:
- Number of Carbon (C) atoms: 1
- Number of Oxygen (O) atoms: 2
For Carbon:
[tex]\[
\text{Carbon valence electrons} = 4 \times 1 = 4 \ \text{electrons}
\][/tex]
For Oxygen:
[tex]\[
\text{Oxygen valence electrons} = 6 \times 2 = 12 \ \text{electrons}
\][/tex]
Adding them together gives the total number of valence electrons:
[tex]\[
\text{Total valence electrons} = 4 + 12 = 16 \ \text{electrons}
\][/tex]
3. Evaluate the proposed Lewis structure:
- The correct total number of valence electrons for this molecule must be 16.
- If the proposed Lewis structure does not contain exactly 16 valence electrons, it is incorrect.
### Conclusion
Based on the total number of valence electrons calculated, the correct number of valence electrons for a molecule containing one Carbon (C) atom and two Oxygen (O) atoms is [tex]\(\boxed{16}\)[/tex].
In the context of the given table:
- The correct number of valence electrons is: [tex]\(16\)[/tex]
If the proposed Lewis structure does not match this requirement, then:
- No, it has the wrong number of valence electrons.
Therefore, the final filled table should look like this:
\begin{tabular}{l|l}
proposed Lewis structure & \multicolumn{1}{|c}{ Is the proposed Lewis structure reasonable? } \\
Yes. \\
No, it has the wrong number of valence electrons. \\
The correct number is: [tex]$\boxed{16}$[/tex] \\
No, it has the right number of valence electrons but doesn't satisfy the \\
octet rule. \\
The symbols of the problem atoms are: [tex]${}^*$[/tex]
\end{tabular}
This confirms whether the structure is reasonable or not based on the valence electrons calculated.
