Only mercury metal as liquid at room temperature and non metal bromine none metal others metals are solids.

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).

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.

Hg is also liquid at room temperature.

Francium is a metal it kept app. The Melting point is 300k so I think the question is not valid.

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 a man made element.

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.
