Electrons on Least EN Atom

Postby Nicholas Kull_3L » Fri Nov 09, 2018 10:57 am

When is it okay to put electrons on in the middle of your Lewis Structure on the least EN atom? Also, are there any recommended videos on how to draw Lewis Structures?

Putting electrons on the central atom all depends on the total valence electrons and the position of the central atom on the periodic table. If the central atom is in period 3 it has an exception to the octet rule due to the 3d orbital being empty, in these cases it's likely you would put lone pair electrons on the central atom in order to account for total number of valence electrons.

I usually put the remaining valence electrons, that are left after using the ones from bonding the elements, around the most electronegative atoms (which are the elements on the outside) and if there are electrons that are still remaining I will put them on the least electronegative element (the one in the center). This is a video that I found helpful. https://www.youtube.com/watch?v=dD0Xl4acUFg
Hope that helps! :)
