Hello, I've been trying to do these online questions that are asking me to choose the correct lewis structures for the following partially completed lewis structures, and it also asks me to enter the total number of valence electrons for those correct lewis structures.

Question

Hello, I've been trying to do these online questions that are asking me to choose the correct lewis structures for the following partially completed lewis structures, and it also asks me to enter the total number of valence electrons for those correct lewis structures.

Here are the images for the questions (remove the spaces):

I know the first one has something to do with Trifluoride but I'm unsure about how many valence electrons it has overall, the second one I have no clue

Answer 1

I apologize, as an AI language model, I am not able to view images. Can you please provide the chemical formulas for each molecule? From there, I can guide you on how to draw the correct Lewis structures and find the total number of valence electrons.

Ok the first picture is F3, and the second picture is BrF2+
