Re: Bond length
Bond length depends on the atoms bonding, so there is really no way for you to know without actual experimentally finding it. You can usually guess bond angle though, thanks to VSEPR theory.

Re: Bond length
I believe you are not able to calculate the bond length without through experiment. But single bonds are the longest, followed by double bonds, and the shortest are triple bonds!

Re: Bond length
To determine bond length, you would have to be given experimentally derived atomic radius. The bond length of a bond would be the radius of both atoms totaled up. This would be the internuclear distance and the length of the bond.

Re: Bond length
Hello! In order to detemrine the bond length we would have to consider the atomic radius. Utilizing the atomic radius, we would total the radius of the atoms up. If the bond in question is a covalent bond we would both the radius of the covalent bond and we would do the same for an ionic bond.

Re: Bond length
We use VESPR theory and our knowledge of different compounds and their bond lengths, but I've only ever heard of it being done with a computer.

Re: Bond length
The length of the bond can be determined by the number of bonded electrons (i.e. the bond order). The higher the bond order, the stronger the pull between the two atoms and the shorter the bond length. The length of the bond between two atoms can also be thought of as the sum of the covalent radii of the two atoms.
Re: Bond length
Does it matter if we have an ionic bond or covalent bond? Would we still calculate it the same way?
Re: Bond length
you don't really know it since they are specific to molecules and you want to calculate it plus he said we didn't need to know that

Re: Bond length
Bond length is usually not calculable without certain information but in general, singly bonds have the longest bond length whereas it gets smaller and smaller as bonds between the atoms are added.

Re: Bond length
I don't think you are required to calculate bond length, but just remember that single bonds are the longest. Using VESPR, you can appproximate bond angles though

Re: Bond length
We are unable to determine bond length without knowing the atomic radius. However, we do know that single bonds are the longest, followed by double bonds, and triple bonds are the shortest.
