Do metal atoms have dispersion force?

In summary, according to the textbook by Tro (6th ed), all atoms and molecules have dispersion forces due to their electrons. However, metal atoms, which are held together by electrostatic forces, may also have London-dispersion force. This is often modeled as a liquid of unbound electrons known as a Fermi liquid. The analysis of the dielectric function of metals also supports the existence of dispersion forces. A key reference for this is an article by Dzyaloshinskii.

Homework Statement


Do metal atoms, such as Ti and Na, have London-dispersion force?2. The attempt at a solution
In the textbook by Tro (6th ed), "Since all atoms and molecules have electrons, they all have dispersion forces." But metal atoms are held together by electrostatic forces. I think there might not be any London-dispersion force.

They have. In metals, the dispersion forces are often modeled as those of a liquid of unbound electrons (Fermi liquid). Formally, dispersion forces result from the analysis of the dielectric function of the metals.
The ultimate reference is an article by Dzyaloshinskii:

1. What is a dispersion force?

A dispersion force is a weak intermolecular force that occurs between two non-polar molecules or atoms. It is also known as London dispersion force or Van der Waals force.

2. Do metal atoms have dispersion force?

Yes, metal atoms do have dispersion force. Even though metals are generally considered to be polar, they do have weakly polarized electron clouds that can induce temporary dipoles in neighboring atoms or molecules, leading to dispersion forces.

3. How does dispersion force affect the properties of metal?

Dispersion force can affect the physical properties of metals, such as melting and boiling points, as it contributes to the overall intermolecular attraction between metal atoms. It also affects the strength of metallic bonds, making them stronger and more stable.

4. Can dispersion force be manipulated in metal atoms?

Yes, dispersion force can be manipulated in metal atoms through various means, such as changing the temperature or applying external pressure. These factors can affect the strength of the dispersion force and ultimately impact the properties of the metal.

5. How does the size of metal atoms affect dispersion force?

The size of metal atoms can affect dispersion force, as larger atoms have more electrons and a larger electron cloud, making them more polarizable and increasing the strength of dispersion forces between them. However, other factors such as shape and arrangement of atoms also play a role in determining the strength of dispersion force in metals.
