I'll cover how to properly draw lewis structures of regular molecules and lewis structures of ions. We will also go over what the octet rule is and all the exceptions that go along with this. Plus we will talk about the valence electrons you will need to memorize for your next chemistry exam.

I just wanted to say that I am 48 years old and I am not totally confident that I can finish my AA. I am taking Foundation of Chemistry. To my surprise, it is not just Chem, it's also Organic Chemistry and Physics. Because of life and adversity, my grades are not great. I am still working on bringing my GPA to 2.0. After 3 semesters, taking 1 to 2 classes each, my GPA is now 1.994 from 1.389. I was told by an planning advisor last year that I will NEVER make it into Medical School. This semester is off to a rocky start. But watching your video, I am actually excited. I took a quiz Friday and didn't pass it, but I still got a higher grade than I have before. I recognized most of the questions. It was only 5 of them, but if I had spent more time (more than 4 hour before the quiz was due) on watching your video and practiced, I believe that I would have passed it. I am horrible at taking test, no matter how much I studied. I have tested anxiety because of my low confidence in learning, absorbing and test taking. So today I watched a few of your videos from the beginning. I am going to do that everyday this week. I have a test due on Friday March 5th. I wish I could find the words that can express my appreciation for you and your videos. I am so scared, but I actually understand what I am learning from you. Thank you so much and I hope I don't offend you, but God bless you.

Hi Melissa! First off thank you for all your content - It's helping me a ton in my 8week summer session of college gen chem. I have a question about the final two structures. When I drew my structure for ClO4-, I tended to want to draw my Cl atom with double bonds for 3 out of 4 of the Oxygen atoms and a single bond to the 4th Oxygen atom. The single electron hanging around by itself on the outside of Oxygen kind of made sense in my mind because the whole molecule in the end was supposed to be negatively charged. My main focus was making sure that the central Cl atom had 7 electrons attached to it. I'm not understanding how its okay to leave a central Cl with only 4 electrons when it's supposed to have 7. I hope that wasn't too confusing of an explanation. Is it like a law of physics no-no to have a single electron hanging out by itself on an exterior element or something? Thanks for any insight!
