There room 8 elements that room liquid at or near room temperature. (images: Dnn87; W. Oelen)

Most that the aspects of the regular table space solids, a few are gases, and there are only two liquid aspects at room temperature and also pressure. A complete of six liquid aspects exist between room temperature and body temperature. There are eight liquid elements, if you incorporate predictions because that recently-discovered artificial elements.

You are watching: What is the only metal that is a liquid at room temperature

Liquid facets at 25°C


Mercury is the only steel that is a liquid element at room temperature. (Tavo Romann)

Room temperature is loosely identified as a temperature in between 20°C or 25°C.The 2 liquid elements at room temperature space mercury (symbol Hg and atomic number 80) and also bromine (symbol Br and also atomic number 35).

Mercury is the only steel that is a fluid at room temperature. It is a shiny, silver metal with a melting allude of 234.3210K​(−38.8290°C, ​−37.8922°F) and also boiling suggest of 629.88K ​(356.73°C, ​674.11°F). The factor mercury is a fluid is due to relativistic effects. Basically, the s-shell electron are relocating so quickly around the atomic nucleus the they behave as if lock were much more massive than slower-moving electrons. Together a consequence, mercury atoms tie weakly to each other and also are easily driven apart when the temperature rises and also kinetic power increases.


Bromine is the only nonmetal the is a liquid at room temperature. (Alchemist-hp)

Bromine is the only nonmetallic element on the regular table that is a liquid near room temperature. Bromine is a halogen that occurs together a reddish-brown liquid together the diatomic molecule Br2. That is melting suggest is 265.8K​(−7.2°C, ​19°F), if its boiling allude is 332.0K ​(58.8°C, ​137.8°F). Bromine is a liquid due to the fact that its external electrons are far-off from that nucleus. So, bromine atoms are quickly influenced by intermolecular forces, making the facet a liquid rather than solid in ~ room temperature.

Elements That are Liquid 25°C-40°C

At contempt warmer temperatures, four added elements space liquids, pass the full of aspects that space liquids at plain temperatures come six. In stimulate of raising melting point, these aspects are:

Mercury (234.32 K)Bromine (265.8 K)Cesium (301.59 K)Gallium (303.3 K)Rubidium (312.46 K)

Mercury, francium, cesium, gallium, and rubidium room metals. Bromine is a nonmetal (halogen).

Francium is the most electropositive of the elements. The melting point is known, yet so tiny of the element exists it’s i can not qualify a photograph of the metal in its fluid state will be take away anytime soon.


Cesium is a soft reactive metal. Like francium, it has actually a high electropositivity or low electronegativity. The reason cesium and also francium room soft and also have low melt points is as result of the size of your atoms, which way the outer electron shell is much from the atomic nucleus. Although cesium go not have actually the highest atomic number of any element, that is atoms room the largest.

Gallium is a gray metal that you deserve to melt in the palm of her hand from human body heat. The element is offered as a substitute because that mercury in the “beating heart” chemistry demonstration. Spoons do from gallium bend once held and also melt in hot liquids.

Rubidium is a soft, silver-colored metal. It is reactive and also spontaneously ignites in waiting to form rubidium oxide. Like cesium (and presumably francium), rubidium violently reacts with water.

Predicted liquid Elements

Copernicium (atomic number 112) and also flerovium (atomic number 114) are fabricated radioactive aspects that researchers predict are liquids in ~ room temperature and also pressure. The suspect melting point of copernicium is around 283 K (50°F), while the guess melting suggest of flerovium is 200 K (-100°F).Both copernicium and flerovium boil and also become gases at temperature well beyond room temperature.

More liquid Elements

Technically, any element deserve to be a liquid. The allude at i beg your pardon an element changes native a heavy or gas to a liquid depends on its phase diagram. The step diagram mirrors that state that matter based upon temperature and pressure. Enhancing temperature is one means to melt a solid right into its liquid, but controlling pressure also works. Because that example, the halogen chlorine becomes a fluid at room temperature once pressure is increased.
