I Am The Only Metal That Is A Liquid At Room Temperature

The most well known is mercury hg which is molten above 38 8 c 234 3 k 37 9 f.

I am the only metal that is a liquid at room temperature. It also has the lowest melting point and boiling point of any other metal. Mercury is the only metal that exists as liquid at room temperature. Elements that are liquid at 25 c. Room temperature is a loosely defined term that can mean anywhere from 20 c to 29 c.

For science it s usually considered to be either 20 c or 25 c. Actually gallium liquifies just above ordinary room temperature. However mercury is a very toxic element and for safety reasons consumer use of mercury in thermometers has become less. Taking room temperature to be 25 0c mercury hg is the only metal that is liquid at room temperature.

Mercury is used to make thermometers barometers and many other scientific instruments. While mercury is the only liquid metal at room temperature the elements gallium cesium and rubidium melt under slightly warmer conditions. It can be obtained by heating cinnabar hgs the sulphide ore of mercury. At this temperature and ordinary pressure only two elements are liquids.

The previous answer concerned common metals. A few elemental metals are liquid at or near room temperature. Mercury is the only metal that is liquid at room temperature. Bromine is liquid at room temperature.
