Van der Waals potential
Okay kiddo, imagine you have two magnets. You know how they attract or repel each other depending on whether the poles are the same or opposite, right? Well, atoms and molecules have something similar - something called electric charges.
But here’s the thing, these atoms and molecules are not those simple magnets like the ones you have. They are more complex and their charges can be distributed unevenly. So, they can attract or repel each other in more complicated ways than the simple magnets.
When they get close to each other, their charges start to interact in a special way that we call the van der Waals force - this is what we call the van der Waals potential. This force can be attractive or repulsive, depending on the type of interaction between the atoms or molecules.
So, remember those two magnets we talked about? Now imagine you have one that is big and the other is small, well the same is true for atoms and molecules. The size of the atoms and molecules can create differences in the distribution of their charges, and this can create a temporary attraction or repulsion between them.
This van der Waals force is very important in all sorts of things, from the way gases behave to how geckos can stick to the walls. It’s like a sneaky force that can have a big effect on things even when we can’t see it!
