There room 8 aspects that room liquid at or close to room temperature. (images: Dnn87; W. Oelen)

Most of the elements of the routine table space solids, a few are gases, and there are just two liquid aspects at room temperature and also pressure. A full of six liquid facets exist between room temperature and also body temperature. There room eight fluid elements, if you include predictions for recently-discovered synthetic elements.

You are watching: Which element is a nonmetallic liquid at room temperature

Liquid elements at 25°C


Mercury is the only metal that is a liquid facet at room temperature. (Tavo Romann)

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

Mercury is the only metal that is a liquid at room temperature. That 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 liquid 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 more massive 보다 slower-moving electrons. As a consequence, mercury atoms bind weakly to each other and are easily driven apart when the temperature rises and kinetic power increases.


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

Bromine is the only nonmetallic aspect on the periodic table that is a liquid near room temperature. Bromine is a halogen the occurs together a reddish-brown liquid as the diatomic molecule Br2. Its melting point is 265.8K​(−7.2°C, ​19°F), if its boiling suggest is 332.0K ​(58.8°C, ​137.8°F). Bromine is a liquid since its outer electrons are distant from its nucleus. So, bromine atoms are quickly influenced through intermolecular forces, making the element a liquid fairly than solid in ~ room temperature.

Elements That room Liquid 25°C-40°C

At slightly warmer temperatures, four added elements space liquids, bringing the full of aspects that space liquids at simple temperatures to six. In order of raising melting point, these elements 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 space metals. Bromine is a nonmetal (halogen).

Francium is the most electropositive of the elements. Its melting point is known, but so tiny of the element exists it’s i can not qualify a photo of the steel in its liquid state will certainly be taken anytime soon.


Cesium is a soft reactive metal. Like francium, it has actually a high electropositivity or short electronegativity. The factor cesium and also francium are soft and have low melting points is due to the dimension of their atoms, which way the outer electron shell is far from the atomic nucleus. Back cesium go not have the highest possible atomic variety of any element, that atoms space the largest.

Gallium is a gray metal that you have the right to melt in the palm of your hand from human body heat. The element is provided as a substitute because that mercury in the “beating heart” chemistry demonstration. Spoons do from gallium bend as soon as held and melt in warm liquids.

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

Predicted fluid Elements

Copernicium (atomic number 112) and also flerovium (atomic number 114) are man-made radioactive elements that researcher predict room liquids in ~ room temperature and also pressure. The predicted melting point of copernicium is about 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 in ~ temperature well past room temperature.

More liquid Elements

Technically, any kind of element have the right to be a liquid. The suggest at i beg your pardon an aspect changes from a hard or gas come a liquid counts on its step diagram. The phase diagram shows that state that matter based on temperature and also pressure. Boosting temperature is one means to melt a solid right into its liquid, but controlling pressure additionally works. Because that example, the halogen chlorine i do not care a liquid at room temperature as soon as pressure is increased.
