Lewis Structure Format
At the review sessions today, all of the examples done were covalent molecules/compounds. I know that there were several examples in the textbook and in class that were done with brackets. Would those all be considered ionic, and if so would you just use electronegativity trends to determine whether or not it should be written in brackets? Thanks in advance!

Yes, ionic Lewis structures are surrounded by brackets and then the charge is indicated on the outside. Also to determine if a structure should be in brackets, I would use the electronegativity trend as you suggested

Re: Lewis Structure Format
To clarify, when there is a bracket with a charge around a Lewis structure with multiple atoms, that means that the molecule shown is a polyatomic ion.
The bonds between the atoms within the ion itself are covalent, but the ion will form ionic bonds with other ions.
When there are bonds shown as lines in Lewis structures, assume those lines represent covalent bonds.
