Question
**Title: Exploring Electron Affinity in the Periodic Table**

**Values:**

- Li⁺: -0.864
- Be⁺: -1.49
- B⁺: -1.33
- C⁺: -1.81
- N⁺: -2.33
- O⁺: -2.18
- F⁺: -2.79
- Ne⁺: -3.46

Units: aJ (attojoules)

**Questions for Consideration:**

1. Why are all of the values negative?
   
2. Why does the Electron Affinity (of the 1⁺ cations) generally increase in magnitude as you go from left to right across the second row of the Periodic Table?

3. Why are B⁺ and O⁺ exceptions? 

---

In this exercise, we explore electron affinity trends for cations across the second row of the Periodic Table. Understanding these trends is crucial for interpreting chemical behavior and reactivity.
