WebYeah, dimers of noble gas atoms are stable due to dispersion aka London forces.More generally, neutral, non-polar molecules can still form very weak bound states arising entirely from the induction and interaction of instantaneous dipole moments (that is, fluctuations in the electron density around an atom arising from the motion of electrons). WebTo give a helium atom nonzero angular momentum requires about 21.2 eV of energy (that is, 21.2 eV is the difference between the energies of the lowest-energy or ground state and the lowest-energy state with angular momentum). ... (The results for other monatomic gases, and for diatomic gases rotating around the axis connecting the two atoms ...
