In this part, we need to know the relationship or to identify what is columns law.
00:10
Take note that this is applicable for two changes point.
00:16
The distance separating between this changes point, this changes point, and their electrostatic force, and their electrostatic force of attraction on repulsion.
00:52
So for example, i have a nine protons.
00:57
So this would be irreversible and i have also nine electrons.
01:02
So this is an attraction.
01:05
So this would be an attraction electrostatic.
01:12
And from the other one, i have also nine electrons and another nine electrons.
01:20
So definitely this would be a repulsion because there are not an opposite charges.
01:28
They are the same charge, which is negative and negative.
01:32
So this would be repulsion, electrostatic force.
01:39
So now, n, this part is n.
01:43
N means the distance.
01:46
So from attraction electrostatic force, so this would be an opposite charge of each other, and they have the same charge of each other.
02:02
Now, from the equation, so the equation that we can use, so equation, so we can have the columbic force, that would be k so we have k over q1 q2 over we have our n raised to the power of r so our n is the distance between to this change particles particles the q1 is the charge so this would be the charge of one particle while the q2 is the charge of other particle we have other particle and k is the column constant so we have the column constant now take note that columns law is applicable for point change but not for all change distribution one that we can describe or we can explain is the london dispersion force so take note that london dispersion force is the weakest intermolecular force for example a type of weak attraction force on bander walls so example example of london dispersion that would be fluorine and i these two are halogens.
04:02
We have also neon and we have also argon.
04:06
These two are noble gas or noble gases.
04:11
Other non -polar molecules such as carbon dioxide.
04:15
Also mothball materials such as naphthalene.
04:20
So for explanation about this one, let's have the iodine, or that would be a diatomic molecule, which has two atoms.
04:32
So your iodine will have no attraction force.
04:39
So we have two types of polarization, the non -polarization.
04:46
And so we have non -polarization, or we have one polarization, which is the non -polarization.
04:54
So this would be our a, and another b, this is also a non -polarization...
