- In this video, Mr. Krug shows how some molecules have multiple resonance structures. He also shows students how to calculate the formal charge of each atom in a molecule and how to use formal charge to determine which Lewis diagram will represent the most stable structure for a molecule.

You do a great job in these videos explaining the concepts simply while going through several applications. Thank you!
Thanks for your kind comments, and thanks for watching!
These videos are so helpful! Tysm!!!
I'm so glad my videos are helpful to you. Keep up the good work!
at 1:11 you have two regular covalent bonds and one coordinate covalent bond
I like you video!
Thank you!
Wait so does college board allways accept if you don't put in into the Formal Charge version?
Usually they do, unless the question specifically refers to multiple possibilities of a structure or if it specifically references formal charge.
You are incorrect regarding the formal charge. The formula for formal charge is the number of valence electrons-nonbonding electrons-(bonding electrons/2). I hope you fixed it, because I referred to your method on my test, and failed, don't want others to do the same.
The formula you placed in your comment is what I demonstrate in my video. In our count, taking (bonding electrons / 2) is EXACTLY the same as counting a shared pair of electrons as a ‘1’. I’m not sure why you failed, but it wasn’t because you used my method to calculate formal charge.
@@JeremyKrug You need to be more specific as to what the formula is. Go back and rewatch your video: it could easily be mistaken that all you have to do is subtract the valence electrons of the atom by the assigned number of atoms. Fix it pls, as I'm sure that I'm not the only one that would mistaken your intent.
No people definitely wouldn't have mistaken Mr Krug's intent. It is just your ignorance when watching the video that you 'failed' your test. Maybe you should have paid more attention in class, or to the video, and you wouldn't have failed. Don't blame Mr Krug for your lack of attention and understanding. Your comment made me LOL. Clown. @@SmhBigPG13
He isn't incorrect. There are multiple ways to explain numerous concepts, and it is your fault for not paying proper attention to his wording. You do realize that bonding electrons/2 is the same thing as counting a shared pair of e- as 1 right? Pay better attention. It's a good thing that you failed your test, maybe next time you'll be more careful. Dont blame him for your shortcomings clown.
