Dots in Lewis Stucture
Hello! When placing the dots (electrons) around the element, does it matter where we place them first? For example in Carbon do we go clockwise from the left side or does it really not matter when placing the dots? Thanks!

Re: Dots in Lewis Stucture
It generally doesn’t matter for now since we haven’t gotten into formal charge, so just put them anywhere around the element

Re: Dots in Lewis Stucture
Yeah it doesn't matter where you place them but it needs to be placed symmetrically.

In class last week Lavelle said that arrangement of the dots does not really matter but the location bond is between the two atoms is important.

Re: Dots in Lewis Stucture
So for problem 2B3 part d, the diagram in the back shows that there are three bonds between Fluorine and Bromine, but there are also 2 pairs of electrons. Typically aren't there only dots in four pairs or sets of bonds?

Re: Dots in Lewis Stucture
There is no order, although you should have one electron on each of the four sides before having two on the same side. You should also take a look at/aim for symmetry (having two on the right side, as well as the left side if the element has six valence electrons).
Re: Dots in Lewis Stucture
I would say that although the placement doesn't necessarily matter in the Lewis Structure, as a rule of thumb make sure that your placement next to the other atom is precise because that's where your bond will be and it makes it less visually confusing for grading. Fill out the other 3 sides before you do the electrons next to the bonded atom.

I would say that it doesn’t matter,yet. I would say place one dot on each side before you add a second dot to the side.

Re: Dots in Lewis Stucture
It doesn't matter where the dots are placed as long as they're distributed as evenly as possible.

Re: Dots in Lewis Stucture
I think it does matter. You should put electron on each side first and then make the pairs.
Re: Dots in Lewis Stucture
Professor Lavelle said that it does not matter what order you place the dots in class. However, you should make sure that there are at least 4 electrons before pairing them together.

Re: Dots in Lewis Stucture
I don't believe it matters, as long as the amount of electrons are correct.

Re: Dots in Lewis Stucture
The order doesn't matter but first put one electron on each side and then start adding more when you have filled all sides with 1 electron.
