Step 1:
I'll solve this problem step by step, following the specified LaTeX formatting guidelines:

Step 2:
: Determine the electron configuration of Aluminum

- Its electron configuration is $$1s^{2} 2s^{2} 2p^{6} 3s^{2} 3p^{1}
- Aluminum's atomic number is 13

Step 3:
: Count valence electrons

- Valence electron count: $$2 + 1 = 3$$ valence electrons
- Valence electrons are in the outermost shell - For Aluminum, these are the electrons in the 3s and 3p orbitals

Step 4:
: Determine how Aluminum achieves a full outer shell

- By losing $$3$$ electrons, it forms a $$3^{+}$$ ion
- A full outer shell requires 8 electrons

Final Answer

- Aluminum has 3 valence electrons - The easiest way for Al to acquire a full outer shell is to lose 3 electrons, forming an ion with a 3^{+} charge
