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). WebFor a monoatomic ideal gas, the adiabatic constant is 5/3, and for a diatomic gas (such as nitrogen and oxygen) adiabatic constant is 7/5. For molecules with three atoms, it is 4/3. With an adiabatic constant 5/3 and molecular mass 4 g/mol for helium, the sound speed at 20C is 1007 m/s. That's why the voice in helium sounds so funny.
