Which metallic element is liquid at room temperature

Copernicium atomic number and flerovium atomic number are man-made radioactive elements that researchers predict are liquids at room temperature and pressure. Both copernicium and flerovium boil and become gases at temperature well beyond room temperature. Technically, any element can be a liquid. The point at which an element changes from a solid or gas to a liquid depends on its phase diagram. The phase diagram shows that state of matter based on temperature and pressure.

Increasing temperature is one way to melt a solid into its liquid, but controlling pressure also works. For example, the halogen chlorine becomes a liquid at room temperature when pressure is increased. Search for:. Mercury is the only metal that is a liquid element at room temperature. Tavo Romann. Bromine is the only nonmetal that is a liquid at room temperature. Related Posts. Cesium symbol Cs and atomic number 55 , a soft metal that violently reacts with water, melts at The low melting point and softness of francium and cesium are a consequence of the size of their atoms.

In fact, cesium atoms are larger than those of any other element. Gallium symbol Ga and atomic number 31 , a grayish metal, melts at Gallium can be melted by body temperature, as in a gloved hand. This element displays low toxicity, so it's available online and may be used safely for science experiments. In addition to melting it in your hand, it can be substituted for mercury in the "beating heart" experiment and can be used to make spoons that vanish when used to stir hot liquids.

Rubidium symbol Rb and atomic number 37 is a soft, silvery-white reactive metal, with a melting point of Rubidium spontaneously ignites to form rubidium oxide. Like cesium, rubidium reacts violently with water. The elements copernicium and flerovium are man-made radioactive elements.

Not enough atoms of either element have been made for scientists to know their melting points for certain, but predictions show both of these elements form liquids below room temperature. Both elements boil well above room temperature. That state of matter of an element may be predicted based on its phase diagram.

While temperature is an easily controlled factor, manipulating pressure is another way to cause a phase change. When pressure is controlled, other pure elements may be found at room temperature. An example is the halogen element chlorine. Actively scan device characteristics for identification. Use precise geolocation data. Select personalised content. Create a personalised content profile.
