### e density

is every bond and lone pair considered a region of electron density?

### Re: e density

Not sure exactly what you mean, but generally I'd say yes? Depends on what the Lewis structure looks like

### Re: e density

Yes, every bond and lone pair are considered regions of electron density. However, a double bond is only one region of electron density and a triple bond is only one region of electron density. Hope that makes sense!

### Re: e density

Yes, you consider lone pairs and bonding pairs as regions of electron density. You only count double and triple bonds as one region however, because you're only considering the regions of electron density not the bond types themselves.

### Re: e density

Yeah! Electron are not locked into position, so the two electrons in a lone pair would be moving around, creating the region of electron density. This region is larger than the one found in a bonding pair of electrons, since it is only attracted to one region of charge (the nucleus), so it would be able to move more freely.

Yes! Every bond and lone pair is an area of electron density. However, double and triple bonds do not count as separate areas of electron density but instead are a single area of electron density.

Hi! Yes, every bond and lone pair are considered a region of electron density. Every bond only counts as one area of electron density regardless of whether it is a single, double, or triple bond.

Hope that helps!

Yes. Every bond and lone pair is a region of electron density. However, it doesn't matter if the bond is a double or triple bond. It is still one region of electron density either way.

### Re: e density

Yes. A region of e- density can either be considered bonding or non-bonding. e- in a covalent bond are counted as a single region, regardless of whether it's a single, double, or triple bond. Non-bonding regions are the lone pairs (each pair is counted as one non-boding region) on the central atom.

### Re: e density

Regions of electron density are counted by adding the number of lone pairs (not each electron in the lone pair) to the number of bonded atoms. For example, H2O has 4 regions of electron density.

### Re: e density

Regions of electron density count as both the bonding and non-bonding parts of a compound. The bonding parts, which are covalent bonds, are counted as one region of e- density regardless of being single, double, or triple bonded. The non-bonding parts, which are the lone e- pairs, are also considered one region of e- density. These e- density regions determine the molecule's shape.

Yep! I think regions of electron density accounts for both bonded regions and lone pairs.

Hope it helps!

### Re: e density

A bonding area and a region with a lone pair are considered regions of electron density. Moreover, keep in mind that having a single bond versus having a triple bond doesn't change whether an area is a region of electron density. Hope this helps!

### Re: e density

Yes, every lone pair and every bond is considered to be one region of electron density. Double bonds and triple bonds count as one as well. More bonds does not equal more regions of electron density.

Yes, every bond is considered a region of electron density. Remember that a double bond and triple bond are bond considered one region of electron density, even though there is more than one bond.

Yes, both bonds are lone pairs are considered areas of electron densities. Even though there are more electrons in double and triple bonds, they are still considered only one area of electron density.

Yes, regions that would be counted as an electron density region is the number of bonding regions and also lone pair areas.

### Re: e density

every bond and lone pair are seen as their own electron density yes, and on top of that a double bond would count as one electron density

### Re: e density

I believe you are correct. A bonding region and a region with a lone pair are considered regions of electron density. Having more than one bond does not change the amount of electron density.

### Re: e density

Yes a lone pair is a region of electron density as well as a bonded pair. Single, double and triple bonds are all one region of electron density, but have diff numbers of pi and sigma bonds.

Yes! Each bond and each lone pair are considered regions of electron density, where electrons are most likely to be found.

### Re: e density

Yes, each bond and lone pair is a region of electron density. However, double and triple bonds both count as a single region of electron density since it is just a type of bond, not 2 or 3 bonds.

### Re: e density

Yes electron density is pretty much a section where electrons are pretty much present. So since bonds and lone pairs have electrons they would be denoted as regions of electron density. The more electrons then the higher the electron density.

### Re: e density

Yes every bond and lone pair are a region of e- density. Even if you have two lone pairs on the same atom ( example :o: ), it would be considered to have two regions of electron density
