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!
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?
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).
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.
