Sir, you have proven not everyone can be a good chemistry teacher. I wish those who have difficulty understanding chemistry but have a deep interest in the subject, must watch your videos. You are the best chemistry teacher in the world.

[@wbreslyn]

Thanks for the kind words!

[@codyrivas3426]

I've been cramming for my chem final for days now. You video series has cleared up many concepts others glazed over. Very clear and concise. Please keep up your great work.

[@wbreslyn]

Thanks for your comment, clear and concise is one of my biggest goals when I make videos! --- Dr. B

[@insomxia]

I've been cramming as well and same thing. My professor just glazed over topics and doesnt go in depth not asks if anyone has questions so here I am forced to go through videos after videos on the material we supposedly learnt.

its super simple lol

[@aseeker2269]

@@nahuelhemsi6571 a simple concept can be made unnecessarily complicated if it isn't explained properly. And not everyone learns the same way.

⁠@@aseeker2269this is an old comment but my teacher taught a method that seems unnecessarily complicated. This video explains it in the simplest way possible.

[@Hirun.]

Hey Dr. B, I'm watching your content to prepare for my chemistry exam and have a question about drawing Lewis structures. Can the Lewis structure for the Ozone molecule (O3) be represented as O=O=O with double bonds on each side? 7:20 To other students seeing this comment: Please ignore the valence electrons that are not explicitly shown, as I am unable to type them on my keyboard. Thanks!

[@ravenoxford5835]

thanks to this channel i learn a lot and learn really fast, and now its now very easy to create lewis structure. hope you upload more of this for future generations to learn also.

[@wbreslyn]

Thank you, I will!

[@clarahoward8729]

Thank you so much, I finally understand Lewis Structures!!

[@wbreslyn]

Great to hear!

[@jasonlove8733]

This video is amazingly informative on Lewis structures. Thank u😊👍🏻👍🏻. So as a general rule should you always look at formal charges for any molecule that has an element in period 3 or below?? I would normally think the Lewis structure would have been the correct one for sulfate and phosphate ions and would not have thought to move on to double bonds on one side of the central atom. 🤔🤔🤔

Does it matter where we place the hydrogen when we draw the lewis structure? Like can we put two on the side and one on top, or two on the side and one on the bottom? Like as long as we have three hydrogens, is that okay? Thanks

[@nanaaicha8682]

thank u so much

[@camilavalladares943]

you should use different colors for the atoms of different electrons, because when they´re coordinate covalent bondings is a little confusing, bc you do not know which is which
