In lewis dot diagrams, valence electrons are represented by dots around the atomic symbol. how many electrons should around an aluminum ion?

Explanation:

Hello,

Aluminium is a metal with 13 as its atomic number, in such a way, one could foresee the Lewis structure via its electron configuration:

It is seen that in its last level, 3, there are three electrons, two from and one from , in such a way one states that aluminium has three valence electrons which are equal to the electrons at its outer shell. The Lewis representation for aluminium is shown on the attached picture.

Best regards.

it's filtration, but this is an assumption so my apologies if i got this
