Practice drawing Lewis Structures with answers and explanation. The video covers the basic Lewis structures for a general chemistry class.
The five steps are:
1. Find the total valence electrons for the molecule.
2. Put the least electronegative atom in the center. Note: Hydrogen (H) always goes outside.
3. Put two electrons between atoms to form a chemical bond.
4. Complete octets on outside atoms.
5. If central atom does not have an octet, move electrons from outer atoms to form double or triple bonds.

Lewis Structures are important to learn because they help us understand how atoms and electrons are arranged in a molecule, such as Methane. This can help us determine the molecular geometry, how the molecule might react with other molecules, and some of the physical properties of the molecule (like boiling point and surface tension).

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.

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!

@jasonlove8733 10 месяцев назад

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. 🤔🤔🤔

formal charge is a just a linear formula "valence electrons in free atom - lone pair electrons - bonding electrons/2".

@wendyfriz 2 года назад

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
