The charge of an aluminum ion is typically 3+. This is because the element's atomic number is 13, reflecting the fact that it has 13 electrons and 13 protons. The valence shell of aluminum has three electrons, and per the octet rule, these three electrons are lost resulting in just 10 electronsand 13 protons. Aluminium is located in period 3, group 13, and has an atomic number equal to 13. This tells you that the electron configuration of a neutral aluminium atom must account for a total of 13 electrons. Now, when aluminium forms 3 + cations, Al3+, it loses 3 electrons from its outermost energy shell.

Now, when aluminium forms 3+ cations, Al3+, it loses 3 electrons from its outermost energy shell. In this case, the 3 electrons will come from the third energy shell.
