Please give me the list of all components which are in liquid form at room temperature

Rani said: (Apr 18, 2011)  
whether the liquid will be at cool temperature or hot liquid

Champa said: (Apr 25, 2012)  
Sodium is the right answer.
Francium is solid at room temperature.

What is fracium? why the liquid from at room temperature?

Avinash C M said: (Jun 4, 2012)  
The melting points of alkali metals were plotted and based on the information francium's melting point was extrapolated to less then room temperature.

How many metal is in liquid form at room temperature ?

Ashutosh said: (Jun 23, 2012)  
Mercury & helium are liquid at room temperature.

Deepak said: (Jul 10, 2012)  
In chemistry standard temperature in actually 25 degrees Celsius. At that temp Francium is solid but it does liquefy at 27 degrees.

Obaid said: (Aug 28, 2012)  
Sodium is in liquid state at room temperature.

Unknown said: (Jan 3, 2013)  
Melting point of sodium is 97.83 Celsius and francium 27 Celsius so francium is in liquid state at room temperature.

Mc Sitlhou said: (Jun 16, 2013)  
Sodium is in solid state at room temperature.

Mc Sitlhou said: (Jun 16, 2013)  
Actually seeing, the only elements which are at liquid state at room temperature are Mercury (Hg) and Bromine (Br). But elements like Caesium[Cs]and Gallium (Ga) or Francium (Fr) are in liquid state slightly above the room temperature.

Mc Sitlhou said: (Jun 16, 2013)  
Helium is not a liquid at room temperature. Liquid helium has a boiling point of about 3.2 Kelvin or -266.8 Celsius.

Jainnandish said: (Jul 29, 2013)  
Mercury and bromine is liquid at room temp. But not helium.

Sumit said: (Dec 20, 2013)  
Francium is a chemical element (fr) atomic no. -87.

Aditya Singh said: (Jan 3, 2014)  
Never heard of Francium. I have heard that Mercury and Bromine are liquid temperature and Cesium and Gallium are liquid at a temperature slightly above room temperature.

Still confused ?

I googled it and found that Francium has it's melting point at 27 degree centigrade. Therefore the state completely depends on the room pressure it is kept in. At normal STP (Standard Pressure and Temperature) it is, however, solid!

Two elements are liquid at room temperature :
Bromine & Mercury.

Four elements melt just a few degrees above room temperature :
Francium (Fr).
Cesium (Cs).
Gallium (Ga).
Rubidium (Rb).

Define room temperature?

Uday Sankar said: (Oct 12, 2014)  
Francium's melting point is 27°C.

But the melting point of of sodium is 97.27°C.

Karthik said: (Jan 28, 2015)  
Sodium's Melting point is greater than Francium that's why it is kept under the kerosene to avoid evaporation.

Ramesh said: (Feb 10, 2015)  
Only mercury metal as liquid at room temperature and non metal bromine none metal others metals are solids.

Balaji said: (Feb 21, 2015)  
Standard room temperature is 27°c.

Four elements melt just a few degrees above room temperature.

Francium(Fr), a radioactive and extremely reactive metal, melts around 300 K. The false color image at left shows 10,000 francium atoms in a laser trap. (For more about francium, see the Orozco group's francium research page at SUNY-Stony Brook. ).

Cesium(Cs), a soft metal that violently reacts with water, melts at 301.59 K. Like francium, cesium's low melting point and softness is a consequence of the size of its atoms: Cs atoms are larger than those of any other known element. The positive charge of a Cs+ core is spread over the atom's large surface area, and less energy is required to push Cs atoms out of place in the metal.

Gallium(Ga), a grayish metal, melts at 303.3 K. Gallium's near-ambient melting point is sometimes demonstrated with a picture of a gallium rod liquefying in someone's bare hand. Wear gloves if you try this yourself: Gallium causes skin rashes and can depress bone marrow function.

Rubidium(Rb), another soft reactive metal, melts at 312.46 K.

Lithium, Sodium and cerium are solid at room temperature while francium is a liquid with a melting point of 300 K (270 C or 810 F).

Aditya Raj said: (Apr 27, 2015)  
That is the correct answer Francium. It is liquid at room temperature as well as Br, Cs, Rb, Fr, Ga are also liquid at room temperature.

Vishali Yerra said: (Nov 6, 2015)  
Hg is also liquid at room temperature.

Praveen Kumar said: (Aug 28, 2016)  
Francium is a metal it kept app. The Melting point is 300k so I think the question is not valid.

Vicky Vikrant said: (Oct 19, 2016)  
The only liquid elements at standard temperature and pressure are bromine(Br) and mercury (Hg). Although, elements caesium(Cs) , rubidium(Rb) , Francium(Fr) and Gallium(Ga) become liquid at or just above room temperature.

Srinidhinini said: (Dec 29, 2016)  
Francium is a man made element.

Ravi Pratap Singh said: (Jan 13, 2017)  
Liquids around room temperature.

The only liquid elements at standard temperature and pressure are bromine (Br) and mercury (Hg).

Although, elements caesium (Cs), rubidium (Rb), Francium (Fr) and Gallium (Ga) become liquid at or just above room temperature.

Francium is liquid at room temperature and Cesium has the largest atomic radii.

What is francium? Describe it detail.

Akhila said: (Mar 8, 2018)  
Why francium is liquid at room temperature?

Naina said: (May 26, 2018)  
I think Mercury is the only metal that is liquid at room temperature.

Two metals are in liquid form at room temperature mercury and galium& one non-metal is in liquid form at room temperature Bromine.

Actually, none of these metals is liquid at room temperature i.e. 298k. Only Hg is liquid at 25°c (room temperature).

Hrprt said: (Oct 11, 2019)  
A few elemental metals are liquid at or near room temperature. The most well known is mercury (Hg), which is molten above −38.8 °C (234.3 K, −37.9 °F). Others include caesium(Cs), which has a melting point of 28.5 °C (83.3 °F), rubidium (Rb)(39 °C [102 °F]), francium (Fr)(estimated at 27 °C [81 °F]), and gallium (Ga)(30 °C [86 °F])
