formal charge and VSEPR
when figuring molecular shape, I've noticed that the textbook has Lewis structures that do not have the lowest formal charge. I know it does not matter as much because we can still figure out the shape. For the final do we draw the Lewis structure according to formal charge before figuring VSEPR shape?

Yes, I believe the best habit to keep in mind is to draw the lewis structure with the lowest formal charge before applying VSEPR

Re: formal charge and VSEPR
It's better to do it this way... but does anybody know if it's a necessity to be correct?

Re: formal charge and VSEPR
This is somewhat unrelated, but does VSEPR just refer to the notation? Like AXE4?

VSEPR refers to the notation and also the way of finding the molecular shape from the Lewis structure.

yes, AXE is the VSEPR formula
yes, AXE is the VSEPR formula

Re: formal charge and VSEPR
In determining formal charge, I know it is #valence electrons - #bonds and #lp. But, if there is one set of lone pairs (2 electrons, one Lone pair) would I just subtract 1 ? Or because there are two electrons, would I subtract two?

Re: formal charge and VSEPR
VESPR is used to predict molecular geometry using valence shell electrons
