Does an individual atom of helium have a melting point and why or why not? Yes, the melting point of an individual atom can be measured using advanced techniques such as atomic force microscopy. No, an individual atom cannot be considered a solid or a liquid so there is no temperature at which it can change from one to the other. No, an individual atom is too small to see so we cannot measure the temperature at which it changes from a solid to a liquid. Yes, the melting point of helium is the same whether there is one atom or one mole of atoms.
