Hi: Can you verify if the below answers are correct?

When drawing a Lewis (electron dot) Structure, after connecting the atoms with single bonds, if you notice that you have too few remaining electrons to give every atom an octet, that's an indication that you are going to have to do what?
Answer==>start making double / triple bonds
When is resonance used?----> when a single Lewis structure cannot fully describe the bonding

Start making multiple bonds
Resonance means more than one valid lewis dot structure.
