To analyze the trends of various properties of Group 1A (alkali metals) as we move down the group, we can summarize the changes in the following manner: ### Step-by-Step Solution: 1. **Atomic Size**: - **Trend**: Increases - **Reason**: As we move down the group, the number of electron shells increases, leading to a larger atomic radius. The effective nuclear charge felt by the outermost electrons decreases, allowing the atomic size to expand. ...
