Nitrogen (atomic number 7) and phosphorus (atomic number 15) belong to group 15 of the Periodic Table. Write the electronic configuration of these two elements. Which of these will be more electronegative? Why?

Explanation

### Step-by-Step Solution:

**Step 1: Write the electronic configuration of nitrogen (N).**
- Nitrogen has an atomic number of 7. This means it has 7 electrons.
- The electronic configuration can be determined by filling the electron shells:
- The first shell (K shell) can hold up to 2 electrons, and the second shell (L shell) can hold up to 8 electrons.
- Therefore, nitrogen's electronic configuration is:
