Arrange the following ions in the order of increasing size : `Be^(2+), Cl^(-), S^(2-), Na^(+), Mg^(2+), Br^(-)`

Text Solution

AI Generated Solution

To arrange the ions `Be^(2+), Cl^(-), S^(2-), Na^(+), Mg^(2+), Br^(-)` in the order of increasing size, we can follow these steps: ### Step 1: Identify the number of electrons in each ion. - **Be^(2+)**: Beryllium (Be) has 4 electrons. After losing 2 electrons, it has 2 electrons left. - **Cl^(-)**: Chlorine (Cl) has 17 electrons. After gaining 1 electron, it has 18 electrons. - **S^(2-)**: Sulfur (S) has 16 electrons. After gaining 2 electrons, it has 18 electrons. - **Na^(+)**: Sodium (Na) has 11 electrons. After losing 1 electron, it has 10 electrons left. - **Mg^(2+)**: Magnesium (Mg) has 12 electrons. After losing 2 electrons, it has 10 electrons left. ...
