![**Question 7:** Draw electron dot structures for the following elements: Na, Al, P, Cl, and Ar. Which are most chemically reactive? Which are least chemically reactive?
**Explanation:**
- Electron dot structures, also known as Lewis dot structures, represent the valence electrons of an atom.
- Here's how to draw the electron dot structures for each element:
- **Na (Sodium):**
- Sodium has 1 valence electron. Its electron dot structure is Na·.
- **Al (Aluminum):**
- Aluminum has 3 valence electrons. Its electron dot structure is Al with three dots around it.
- **P (Phosphorus):**
- Phosphorus has 5 valence electrons. Its electron dot structure is P with five dots around it.
- **Cl (Chlorine):**
- Chlorine has 7 valence electrons. Its electron dot structure is Cl with seven dots around it.
- **Ar (Argon):**
- Argon is a noble gas with 8 valence electrons. Its electron dot structure is Ar with eight dots around it.
- **Chemical Reactivity:**
- **Most Chemically Reactive:** Sodium (Na) is highly reactive because it can easily lose one electron to achieve a stable configuration.
- **Least Chemically Reactive:** Argon (Ar) is the least reactive as it already has a complete valence shell, making it stable and inert.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F80366bbd-a758-40e7-b9ec-8d2e3445db54%2F70201e51-bcff-4a20-9d79-e001ed7d1908%2F18w20xp_processed.png&w=3840&q=75)
