Step 2:: Understand Sodium's Electron Configuration
- Electron configuration is $$1s^{2} 2s^{2} 2p^{6} 3s^{1}
- Sodium (Na) is an alkali metal in Group 1 - Neutral sodium has atomic number 11
Step 3:: Determine Na+ Ion's Electron Configuration
- Na+ electron configuration becomes $$1s^{2} 2s^{2} 2p^{6}
- When sodium forms a positive ion (Na+), it loses its outermost electron - This is equivalent to the noble gas neon's electron configuration
Step 4:: Draw Lewis Dot Symbol
- For a positive ion, there are NO valence electrons to represent - The Lewis dot symbol for Na+ will be simply the element symbol Na+ - No dots will be drawn around the symbol
Final Answer
Note: The Lewis dot symbol for Na+ is just the symbol Na+ with no surrounding dots, reflecting its complete loss of the valence electron.
