Basically in the Lewis structure of ionic compound, when Al reacts with Fl, then Aluminum Fluoride is formed which is as follows:
x.
Al + F ------> Al[ :F : ]3-1
..
In this structure, the pair of dots are the representatives of lone pairs and a single dot with x is the bond pair. X is the only electron which is taken from aluminum.
For reference: AlF3
