To compare the characteristics of elements 'A' and 'B' from the 3rd period of the Modern periodic table, we will create a table that summarizes their properties based on the given criteria. ### Step-by-Step Solution: 1. **Number of Electrons in Their Atoms:** - Element A (Group 2): The electronic configuration is 2, 8, 2. Therefore, it has a total of 12 electrons. - Element B (Group 13): The electronic configuration is 2, 8, 3. Therefore, it has a total of 13 electrons. ...
