Step 1:I'll solve this Lewis Dot Diagram problem for Nitrogen step by step:
Step 2:: Understand Nitrogen's Atomic Structure
- Nitrogen (N) is in Group 15 (VA) of the periodic table - Atomic number is 7 - Electron configuration is 1s² 2s² 2p³ - Total valence electrons = 5
Step 3:: Determine Bonding Requirements
- Nitrogen wants to achieve a stable octet (8 electrons) - It needs to share or gain 3 electrons to complete its valence shell - Nitrogen typically forms three covalent bonds
Step 4:: Analyze the Lewis Dot Diagram Requirements
- Must show all 5 valence electrons - Must show correct bonding arrangement - Must follow octet rule
Step 5:: Evaluate the Given Options
- Looking for a diagram with: * Nitrogen atom at center * Three bonds * Total of 8 electrons around nitrogen
Step 6:: Identify the Correct Diagram
- Picture C matches these requirements * Central nitrogen atom * Three single bonds * 8 total electrons around nitrogen
Final Answer
Picture C is the correct Lewis Dot Diagram for Nitrogen.
