So deviations from ideality, which you can take a look at in vanderwals equation, or we can just look at qualitatively, mainly have to do with two things.
00:21
One has to do with the size of the atom, and the other has to do with the intermolecular forces that would be associated.
00:34
Associated with those gases.
00:38
And so if we were to look at fluorine, chlorine, and bromine, as we move between fluorine, chlorine, and bromine, we have increased intermolecular forces.
00:58
Now each of these is non -polar, so we're only really dealing with london dispersion forces, ldfs.
01:08
However, as we increase for london dispersion forces, as we increase the number of electrons that a substance has, we increase their london dispersion forces.
01:21
So if we have a higher number of electrons, we have a higher london dispersion force.
01:27
Now for f2, that contains 18 electrons...
