Step 1:Let me solve this step by step with a detailed explanation about Lewis structures for sodium.
Step 2:: Understanding Sodium's Electron Configuration
- Electron configuration is $$1s^{2} 2s^{2} 2p^{6} 3s^{1}
- Sodium (Na) is an alkali metal located in Group 1 of the periodic table - Its atomic number is 11, meaning it has 11 electrons
Step 3:: Lewis Structure Characteristics for Metals
- For metals like sodium, Lewis structures typically show the valence electron - Sodium has only one valence electron in its outermost shell (3s¹) - In Lewis dot diagrams, this single electron is represented as a single dot
Step 4:: Determining the Correct Representation
- The Lewis structure for sodium will be the letters "Na" with one dot - This single dot represents the lone valence electron in the 3s orbital
Step 5:: Analyzing the Options
- Option A shows "Na" with one dot ✓ - Options B, C, and D show multiple dots, which is incorrect
Final Answer
A (The letters Na with one dot)
