Answer:
See the image below
Explanation:
To draw a Lewis structure for an atom, you locate the element in the Periodic Table and figure out how many valence electrons it has. Then you distribute the electrons as dots around the atom.
Al is in Group 13, so it has three valence electrons.
Al³⁻ has three more valence electrons for a total of six.
The Lewis structure will show six dots around the symbol of the atom and a charge of 3-.
