How is the strength of London dispersion forces related to the number of electrons?

Answer 1

#"More electrons" -> "Larger atom's size"#

London dispersion force (LDF) depends on the surface area of interacted particles. Moreover, more electrons results in larger atoms size and therefore, stronger LDF.

This is also derived from the fact that higher number of electrons will increase the chance of forming what is called induced dipole (also called polarizability) which will make the interactions stronger.

Answer 2

The number of electrons in a molecule or atom determines the strength of the London dispersion forces; that is, the more electrons in a molecule or atom, the stronger the London dispersion forces tend to be. This is because larger molecules or atoms with more electrons have a greater electron cloud, which results in stronger temporary dipoles and stronger London dispersion forces.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
