To find:
The correct Lewis symbol for stable aluminium ion from the given options.

Answer to Problem 4.01VP
Solution:
Option (e) correctly represents the most stable Aluminium ion.
Explanation of Solution
The electron configuration of Aluminium is 1s2 2s2 2p6 3s2 3p1. Aluminium is a group III element, and its atoms form +3 ions by losing all three valence electrons. It has no valence electrons left, so the Lewis structure for it is simply the
So, it is simply Al3+.
Conclusion:
The lack of dots in the structure for Al3+ reinforces the fact that the Al atoms, like those of the other main group metals, lose all their valence shell electrons and form monoatomic cations.
