Dr Bob Although helium atoms do not combine to form He2 molecules
Dr Bob Although helium atoms do not combine to form He2 molecules. is it true to say that He atoms are weakly attracted to one another from London dispersion forces (induced dipole forces) or is there another force at play? It cant be Hydrogen bonding(there is no hydrogen here) it cant be dipole induced dipole forces or ion-dipole forces or even dipole-dipole forces can it ?? Can you clarify for me please Thanks Andy
