Step 1:I'll solve this problem step by step:
Step 2:: Determine the element
- The problem is about an aluminum ion - Aluminum is a metallic element located in Group 13 (IIIA) of the periodic table
Step 3:: Recall aluminum's electron configuration
- Its electron configuration is $$1s^{2} 2s^{2} 2p^{6} 3s^{2} 3p^{1}
- Aluminum's atomic number is 13
Step 4:: Determine ion formation
- When aluminum loses 3 electrons, it becomes a $$Al^{3+}$$ ion
- Metals in Group 13 typically lose electrons to form positive ions - Aluminum tends to lose its 3 outer electrons (3s² and 3p¹)
Step 5:: Verify the charge
- Aluminum loses 3 electrons - This results in a 3 + charge - This corresponds to option B in the given choices
Final Answer
Key Insight: Group 13 metals typically form 3 + ions by losing their outer s and p electrons to achieve a stable electron configuration.
