Drawing Lewis Structures

Postby Meigan Wu 2E » Fri Oct 26, 2018 1:36 am

When drawing a Lewis Structure, how do you know specifically where to bond the atoms? What are the steps to drawing accurate Lewis Structures of atoms bonded together?

You bond the atoms where there is either an excess or lack of valence electrons, you know this by placing the electrons in the structure or by visualizing it. The following are two helpful links with step-by-step instructions:

Atoms can be bonded together in the lewis structure in any pattern, but each main element, other than H, needs to have a full set of 8 electrons by the end. By using single, double and triple bonds, you can use the amount of valence electrons available and start to form the structure, experimenting with the different bonds to find the correct bonds needed.

Here's a video on the basics of Lewis structures: https://www.youtube.com/watch?v=1ZlnzyHahvo
I hope this helps :)
