Drawing Lewis Structure

Postby Bao Tram Nguyen » Sun Oct 27, 2019 12:53 am

I know that the octet rule is important when drawing a lewis structure but is it always necessary to draw the dots for the electrons on each element or can it be inferred that it fulfills the octet rule?

The reason why you draw the dots (lone pairs) of electrons is because it gives a more clear representation since there are expections to the octet rule. However, in the case for Hydrogen atoms since there are only 2 electrons you won't see any dots, only the single covalent bond.

since we've been drawing all of the lone pairs in class and in hw, it's safe to say that yes, you will have to draw those for the exam. however, i remember some teachers using a line instead of dots to represent lone pairs, so if you want to find alternate ways to draw your lewis structures just talk to your TA to see what is considered correct for this class

i would assume we have to draw the lone pairs since we haven't been told otherwise. just draw them to be safe

I believe in this class you have to draw them in order to ensure that each atom gets the right number of electrons in the structure

Drawing them is beneficial in keeping track of the electron figuration and when dealing with finding resonance structures because then the number of valence electrons can vary.

Drawing it all out can help you keep track of the electrons. It's important to draw them when there are lone pairs too.
