AI Generated Solution

To arrange the elements Li, Na, and K in increasing order of their most positive electron affinity, we need to understand the concept of electron affinity and how it varies among these alkali metals. ### Step-by-Step Solution: 1. **Understanding Electron Affinity**: - Electron affinity is the energy change that occurs when an electron is added to a neutral atom in the gas phase. A more positive electron affinity indicates a greater tendency to accept an electron. 2. **Identify the Elements**: ...
