How many electrons are lost from Al3+

1.	How many electrons are lost from Al3+
Answer» 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.
