Chemical Elements With the Lowest Melting Points
Key Findings
About This Dataset
Chemical Elements With the Lowest Melting PointsHydrogen melts at -259.16 C, the lowest of any element that solidifies at ordinary pressure; helium, which never freezes at one atmosphere, is excluded entirely. The list is dominated by light non-metals and noble gases, hydrogen, neon, fluorine, oxygen, nitrogen and argon all melt below -180 C, which is exactly why they are gases in daily life. The heavier noble gases krypton (-157 C) and xenon (-112 C) melt at higher, though still frigid, temperatures. Two outliers close the ranking: chlorine at -101.5 C and mercury at -38.83 C, the only metal here and famously the only metal that is liquid at room temperature. The roughly 220-degree span from hydrogen to mercury illustrates how weak interatomic forces keep these elements from solidifying.
