    Understanding lewis structure answer

    The following picture is a posted solution to an earlier exam, The question was to draw Ca (s) + Br2 (g) = CaBr2 as a lewis structure, the suggested answer was like this: I understand that this forms an ionic bond given that Ca (metal) donated electrons to Br (non metal) and becomes...

    Lewis Structure

    I am having a hard time understanding this, a bond gives 2 electrons to fill octet is what my teacher says. But i see it different, i see a bond taking a SPACE of 2 electrons but each atom connected only gets 1 electron. Let's start with BeCl2 as example: Be has 2 Valence(outer) electrons, and...

    HCO3- Lewis Structure

    I was wondering if there are 2 versions of drawing the Lewis Structure for HCO3-, or if only the top one is correct? If so, could you possibly explain why it is one over the other and how I make that decision? (please see attachment!) Thanks!! :)

    A valid Lewis structure of CS3:

    Hello, I believe this is the last problem on my study guide I have a question about. The question is: A valid Lewis structure of CS3 cannot be drawn. Why? My answer was that a valid structure cannot be drawn because CS3 displays the property of resonance. Am I correct in this...

    Lewis structure for Nitrogen Dioxide

    I was able to come up with a total of 7 possible Lewis structures of Nitrogen Dioxide (NO2). I am convinced that some of them are incorrect but I'm not sure of the reason why. They all count electrons correctly, but their formal charges are different. Which ones are correct and which ones are...
