Step 1:I'll solve this step-by-step using proper LaTeX formatting:
Step 2:: Determine Aluminum's Electron Configuration
- Its electron configuration is $$1s^{2} 2s^{2} 2p^{6} 3s^{2} 3p^{1}
- Aluminum's atomic number is 13
Step 3:: Identify Valence Electrons
* $$3p^{1}$$ contributes 1 electron
- Valence electrons are those in the outermost shell - For aluminum, these are the electrons in the 3s and 3p orbitals - Counting these electrons:
Step 4:: Calculate Total Valence Electrons
- Total valence electrons = $$2 + 1 = 3
Step 5:: Verify Bonding Potential
- Aluminum typically forms ions or bonds by losing these 3 valence electrons
Final Answer
C. 3 valence electrons are available for bonding.
