Question

**Topic: Understanding Electron Affinity**

Arrange the following elements in increasing order of electron affinity:

a) Na, Li, Cs

b) I, Br, F

c) Na, Li, Al, O

---

**Explanation:**

Electron affinity refers to the energy change that occurs when an electron is added to an isolated atom in the gaseous state. Elements with higher electron affinity values tend to gain electrons more easily. The elements are typically arranged based on periodic trends related to their positions in the periodic table.
