Lone Pair E-
Do lone pair e- count as their own regions of e- density? or is it just the atom that's counted?
thank you!
thank you!

Re: Lone Pair E-
Yes, lone pair electrons are also regions of electron density! They have a much stronger force of repulsion than bonding pairs, but both are considered regions of electron density.

Re: Lone Pair E-
Lone pairs are counted as regions of e- density just like atoms. However, they do act differently than bonding atoms because of their high repulsion force which changes the overall shape of the molecule.

Hi, yes, lone pair electrons also count in electron density and will affect the shape of the molecules, but they don't count when naming the geometry of the molecule.

Re: Lone Pair E-
Just like atoms are, lone pair electrons are also considered in the electron density. Their high repulsion force causes them to act slightly different, causing 2 electron pairs needing to be as far away from eachother as possible in a structure.
Re: Lone Pair E-
The lone pair electrons are also considered in the count of electron density, which that will affect the molecules shape. However, it doesn't count when figuring out the geometry of the molecule.

Re: Lone Pair E-
I think one lone pair of e- is counted as one electron density. So for example, like H2O, on the oxygen atom, there are two lone pairs of e- and we say there are four electron density clouds, 2 bonding and 2 lone-pairs.
Hope it helps!

Re: Lone Pair E-
it counts as its own electron density because it region contains electrons. You only look at the elements when determine the basic shape

Yes, lone pair electrons do count and will affect the shape because of their strong repulsion.

Re: Lone Pair E-
Yes even though lone pair electrons are not bonded to anything else they also would be considered a region of electron density. They could also cause repulsion and influences the overall molecule.

Re: Lone Pair E-
Yes, lone pairs are considered their own regions and they repel other regions strongly too. That is why when looking at the shape of molecules we have to consider lone pairs (because they repel the other bonds).

Re: Lone Pair E-
Yes, lone pair electrons are also regions of electron density. If they weren't then, molecular shape would be only determined by bonding electrons.

Re: Lone Pair E-
Yes, they do! Lone pair electrons count as another region of electron density. In fact, they often have a larger electron density than a bond!

Hi, we do count regions of electron density because they affect the shape of the molecule by repelling other regions.

Re: Lone Pair E-
Why are lone pairs more "diffuse" or take up a larger space than bonding pairs do? Since they all are areas of electron density

Re: Lone Pair E-
yes, lone pairs count as their own region of electron density. But when naming a shape, the regions of electron density in bonding are used.

Re: Lone Pair E-
Correct, a lone pair does count as its own region of electron density. Electron density counts for both lone pair electrons and bonding pairs.

Re: Lone Pair E-
yes they count as their own separate region and have a stronger repulsion power than the rest of the regions. the powers go from lone pair to lone pair>lone pair to bonding pair>bonding pair to bonding pair. This will in turn also cause the angles between the other regions to be greater.

Re: Lone Pair E-
Just to reiterate for the 20th time, yes, e- pairs are counted. E- repulsion can influence shape.

Re: Lone Pair E-
Yes, bonds and lone pairs count as regions of electron density and contribute to the overall shape of the molecule.

Re: Lone Pair E-
lone pair e- do count as their own regions of electron density, including when you are creating a VSPER model. In addition, e- are more repulsive compared to bound atoms, which in turn affects the bound angles of a molecule.

Like everyone else has said lone pair electrons do count in electron density as well as affecting the shape of the molecules themselves.

yes!! lone pairs do count as their own region of electron density so they affect the shape of the molecule.

Yep, thus affecting the shape of the molecule. Their repulsion is stronger than bonding pairs.

I agree with everyone above. Lone pairs are their own regions of electron density :)

Re: Lone Pair E-
They most definitely do! in terms of the magnitude of which molecular geometry is affected by other regions of electron density it goes as follows, LP-LP, LP-atom, atom-atom. Lone pairs are not shared and essentially belong to the atom which the LP is assigned, which is why affect vsper so much.
Re: Lone Pair E-
Yes they are considered electron regions. That is why they contribute greatly to bond angles and molecular structure; with their repulsion.

Re: Lone Pair E-
Yes, lone pairs count as their own region of electron density. That is why the shape of a compound is dependent on both the number of outer atoms and the number of lone pairs.

Re: Lone Pair E-
Lone pairs have their own electrical density kind of like a bubble around them that causes repulsion
Re: Lone Pair E-
Yes, Lone Pair electrons do count as an electron density region.

Re: Lone Pair E-
Lone pairs (and also radicals) have their own density. However, they only influence the shape of a molecule in electron geometry, not molecular geometry.
