**Understanding Lewis Structures: Nitrogen Atom**

**Question:**
Which of the following represent the Lewis structure for \( \text{N} \)?

**Options:**
1. \( \text{N:} \)
2. \( \cdot\text{N}\cdot \)
3. \( \cdot\text{N} \cdot \cdot \)
4. \(\text{N}\cdot \)
5. \( \cdot \cdot \text{N} \cdot \cdot \)

**Explanation:**
Lewis structures are representations of molecules showing all the valence electrons as dots. The aim is to depict the distribution of electrons around atoms. Nitrogen (N) has 5 valence electrons. A correct Lewis structure for nitrogen places these five electrons around the symbol “N.”

Here’s an analysis of the options provided:

1. \( \text{N:} \)
    - The "N" has two dots on one side. This implies 2 valence electrons, which is incorrect for nitrogen.

2. \( \cdot\text{N}\cdot \)
    - The "N" has one dot on each side (top and bottom). This shows 2 valence electrons, which is also incorrect for nitrogen.

3. \( \cdot\text{N} \cdot \cdot \)
    - The "N" has three dots around it, which corresponds to 3 valence electrons, incorrect for nitrogen.

4. \(\text{N}\cdot \)
    - The "N" has one dot beside it. This implies 1 valence electron, incorrect for nitrogen.

5. \( \cdot \cdot \text{N} \cdot \cdot \)
    - The "N" has five dots around it in pairs, accurately representing 5 valence electrons for nitrogen.

Hence, the correct Lewis structure for \( \text{N} \) is option 5: \( \cdot \cdot \text{N} \cdot \cdot \).

**Correct Answer:**
5. \( \cdot \cdot \text{N} \cdot \cdot \)
