AI Generated Solution

To write the electron dot structures (also known as Lewis dot structures) for sodium, oxygen, and magnesium, we need to follow these steps: ### Step 1: Determine the number of valence electrons for each element. - **Sodium (Na)**: Sodium has an atomic number of 11. Its electron configuration is 1s² 2s² 2p⁶ 3s¹. Therefore, sodium has 1 valence electron (the electron in the 3s orbital). - **Oxygen (O)**: Oxygen has an atomic number of 8. Its electron configuration is 1s² 2s² 2p⁴. Therefore, oxygen has 6 valence electrons (2 in the 2s orbital and 4 in the 2p orbital). - **Magnesium (Mg)**: Magnesium has an atomic number of 12. Its electron configuration is 1s² 2s² 2p⁶ 3s². Therefore, magnesium has 2 valence electrons (the electrons in the 3s orbital). ### Step 2: Draw the electron dot structures. ...
