which elements are liquid metals?
Weegy: Two elements are liquid at room temperature (298 K): Bromine (Br), an reddish brown liquid with a suffocating odor, melts at 265.9 K. Mercury (Hg), a toxic metal, [ melts at 234.32 K. (See Why is mercury a liquid at STP?) 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. ] User: thanks! Weegy: You're welcome. [smile] (More)
