Text Solution

AI Generated Solution

To draw the Lewis dot symbols for Beryllium (Be) and Boron (B), we will follow these steps: ### Step 1: Determine the Atomic Number and Electronic Configuration - **Beryllium (Be)** has an atomic number of 4. Its electronic configuration is \(1s^2 2s^2\). - **Boron (B)** has an atomic number of 5. Its electronic configuration is \(1s^2 2s^2 2p^1\). ### Step 2: Identify the Valence Electrons - For **Beryllium**, the valence shell is the second shell (n=2), which contains 2 electrons (from the \(2s^2\) subshell). ...
