Explanation:
Explanation:The electron configuration of an aluminum ion, Al3+, is 1s2, 2s2, 2p6. Normally, a neutral atom of aluminum in a grounded state would have 13 electrons. However, aluminum loses three electrons to form the Al3+ ion. These electrons
are lost from the valence electron shell which is the n=3 shell. This leaves the n=3 shell empty and makes the n=2 shell the valence shell. This also gives the ion eight valence electrons in the n=2 shell which satisfies the octet rule.
