Do metal atoms have dispersion force?

Click For Summary
SUMMARY

Metal atoms, including titanium (Ti) and sodium (Na), do exhibit London dispersion forces, despite being primarily held together by electrostatic forces. According to Tro's textbook (6th ed), all atoms and molecules possess dispersion forces due to the presence of electrons. In metals, these forces are effectively modeled as those of a liquid of unbound electrons, known as a Fermi liquid. The theoretical foundation for understanding these dispersion forces in metals is detailed in the article by Dzyaloshinskii.

PREREQUISITES
  • Understanding of London dispersion forces
  • Familiarity with electrostatic forces in metals
  • Knowledge of Fermi liquid theory
  • Basic concepts of dielectric functions
NEXT STEPS
  • Read Tro's textbook on intermolecular forces for foundational knowledge
  • Explore the article by Dzyaloshinskii for advanced insights on dispersion forces
  • Study the properties of Fermi liquids in condensed matter physics
  • Investigate the role of dielectric functions in metals
USEFUL FOR

Students and researchers in physical chemistry, materials science, and condensed matter physics, particularly those interested in the interactions of metal atoms and their electronic properties.

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:
