kelel01 1 #1 February 3, 2006 Please know that I use the term "geek" with the utmost affection. Ok, so here's my question: Regarding Lewis Dot Structures, how many valence electrons does a Carbonate Ion - CO3 2- - have? (That's a subscript 3, and a superscript 2-). Thanks!

labrys 0 #3 February 3, 2006 24 4 for the carbon (1), 6 for each oxygen(3), plus 2 for the overall negative charge of 2 of the ion.Owned by Remi #? Quote Share this post Link to post Share on other sites
kelel01 1 #4 February 3, 2006 I already looked at that page. But thanks! Every method I try, I come up with an answer that's not a choice. But I don't want to list the choices, so as to sway someone to make up an incorrect answer. Quote Share this post Link to post Share on other sites
kelel01 1 #5 February 3, 2006 Isn't that just "electrons"? Although I don't know how "valence electrons" work on a compound. I hate having PRE-tests that count. The concept sucks butt. Quote Share this post Link to post Share on other sites

kelel01 1 #7 February 3, 2006 How'd you get that? 18 and 24 are both choices. Quote Share this post Link to post Share on other sites
mcneill79 0 #8 February 3, 2006 Actually I take that back I think 24 is correct. I was doing something more complicated This site is kind of neat. Quote Share this post Link to post Share on other sites
kelel01 1 #9 February 3, 2006 Yep. 24 is it. Once I reread the explanation in the book, I knew it was right. Thanks for that link, too! Phew. Got my 100 on that pre-test. I was sweatin' that one for a second there. Quote Share this post Link to post Share on other sites

kelel01 1 #11 February 4, 2006 It's actually my favorite class. But that question was giving me fits. And of course now I see how easy it is. Quote Share this post Link to post Share on other sites
