Step 1:I'll solve this Lewis dot structure problem step by step:
Step 2:: Determine Silicon's Electron Configuration
- Electron configuration is $$1s^{2} 2s^{2} 2p^{6} 3s^{2} 3p^{2}
- Silicon (Si) is in Group 14 of the periodic table - Atomic number is 14 - Valence electrons are in the 3s and 3p orbitals - Total valence electrons = 4
Step 3:: Lewis Dot Structure Rules
- Each valence electron is represented by a dot - Dots are placed around the element's symbol - Dots are distributed to maximize single electrons before pairing
Step 4:: Construct Lewis Dot Structure
- Place 4 dots around the Si symbol - Distribute dots singly first, then pair up
Step 5:: Analyze the Given Options
- Option A (Si) has no dots - Option B (Si:) has 4 dots around the symbol
Step 6:: Determine Correct Answer
- Option B (Si:) correctly represents Silicon's Lewis dot structure
Final Answer
Si: The Lewis dot structure for Silicon shows 4 dots around the Si symbol, representing its 4 valence electrons.
