Step 1:Let me solve this step by step:
Step 2:: Understand Lewis Dot Diagrams
- Lewis dot diagrams represent the valence electrons of an atom - Valence electrons are the electrons in the outermost shell - These electrons determine an atom's bonding behavior
Step 3:: Analyze Boron's Electron Configuration
- Boron's atomic number is 5 - Electron configuration is 1s²2s²2p¹ - This means boron has 3 valence electrons in its outer shell
Step 4:: Interpret the Lewis Dot Diagram
- The three dots in boron's Lewis dot diagram represent its 3 valence electrons - These electrons indicate boron's ability to form bonds
Step 5:: Evaluate Bonding Capability
- With 3 valence electrons, boron can bond with three other atoms - This allows boron to form three covalent bonds - Boron typically forms three single covalent bonds to achieve a stable electron configuration
Final Answer
The correct answer is: "can bond with three other atoms."
