How many elements are liquids at room temperature?
Quick Answer
Only 2 elements are liquid at room temperature: mercury and bromine. Gallium and cesium melt near room temperature but are usually solid unless warmed slightly.
The Full Story
At typical room temperature, only two elements are liquid: mercury and bromine. Mercury is the only metal that is liquid at room temperature, while bromine is a nonmetal and one of the few liquid elements. Gallium and cesium melt very close to room temperature, so they can become liquid in a warm hand or a slightly heated room. This rarity makes liquid elements especially memorable in chemistry. Their unusual melting points are linked to how their atoms bond in the solid state.
