Step 1:I'll solve this problem step by step, following the specified LaTeX and formatting guidelines:
Step 2:: Understand Aluminum's Atomic Structure
- Electron configuration: $$1s^{2} 2s^{2} 2p^{6} 3s^{2} 3p^{1}
- Atomic number of Aluminum: 13 - Total valence electrons: 3 (from the 3s and 3p orbitals)
Step 3:: Lewis Dot Diagram for Neutral Aluminum Atom
\begin{array}{c}
- Arrange 3 dots around the Al symbol - Dots can be placed on any side of the symbol - Representation: \cdot \ Al \ \cdot \cdot \end{array}
Step 4:: Lewis Dot Diagram for Aluminum Ion (Al³⁺)
\begin{array}{c}
- Aluminum ion loses 3 electrons to become stable - No valence electrons remain - Representation: Al^{3 +} \end{array}
Final Answer
- Neutral Aluminum Atom: \begin{array}{c} \cdot \ Al \ \cdot \cdot \end{array} - Aluminum Ion (Al³⁺): \begin{array}{c} Al^{3 +} \end{array}
