Web11 de abr. de 2024 · The primary reason for tungsten’s high melting point is its atomic structure. Tungsten atoms are arranged in a crystalline lattice structure with strong covalent bonds between them. This arrangement gives the metal its strength and resilience, which translates into its high melting point. Additionally, the electrons in tungsten’s outermost ... Web13 de mar. de 2024 · The highest melting point (~4236 K) is achieved with the composition of HfC 0.638 N 0.271 , which is ~80 K higher than the highest value in a Hf–C binary system. Dominating mechanism of the N addition is believed to be unstable C–N and N–N bonds in liquid phase, which reduces liquid phase entropy and renders the liquid …

WebI've been trying to understand why NaF has the highest melting point among all of the given solids. I thought it would be NaI as it will have the biggest molar mass among them which would mean it has the strongest intermolecular forces. Is it electronegativity difference or molar mass that you look at when analysing intermolecular forces?
