which elements on the periodic table are liquid at room temperature?
479432
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.

Mercury is the only one in liquid state at room temperature. It's used in thermometers because it has high coefficient of expansion. Hence, the slightest change in temperature is notable when it's used in a thermometer. It also has a high boiling point which makes it very suitable to measure higher temperatures.
347213
The noble gases of Group 8A (He, Ne, Ar, Kr, Xe, and Rn) are all gases at room temperature (as the name of the group implies); since they are all unreactive, monatomic elements, their boiling points are extremely low.
386783
mercury (a metal) has a low melting point and exists as a liquid at room temperature. elements in group 1 have low melting points, but also low densities, for example, sodium is less dense than water and so it floats.

Physical Properties of Metals State: Metals are solids at room temperature with the exception of mercury, which is liquid at room temperature (Gallium is liquid on hot days).
369401
The molecular structure of unsaturated fats makes them liquid at room temperature. Their fat molecules do not stack easily, so they cannot form a solid at this temperature.
97479
The alkali metals are solids at room temperature (except for hydrogen), but have fairly low melting points: lithium melts at 181ºC, sodium at 98ºC, potassium at 63ºC, rubidium at 39ºC, and cesium at 28ºC. They are also relatively soft metals: sodium and potassium can be cut with a butter knife.
382555
All metals except mercury are solids at room temperature. Both the high electrical conductivity and thermal conductivity come from the fact that one or more valence electrons is relatively free to travel throughout the solid material.
731239
State at room temperature Room temperature is usually taken as being 25°C. At this temperature, fluorine and chlorine are gases, bromine is a liquid, and iodine and astatine are solids. There is therefore a trend in state from gas to liquid to solid as you go down the group.
1205627
Their melting and boiling points are generally lower than normal metals. Their electronegativity and conductivity is also higher, but their texture is softer than usual metals. These elements are distinguished from metalloids by their high boiling points compared to that row of elements in the periodic table.
849935
The two carbons on the hydrocarbon molecules each have triple or double bonds, and hydrogens cannot saturate them. This makes the entire molecular structure weaker, so the substance stays liquid at room temperature.
1342277
I presume you mean “What elements are solid at room temperature (and pressure)”. All of them, except the gases hydrogen, nitrogen, oxygen, fluorine and chlorine, the “noble” gases helium, neon, argon, xenon, krypton and radon, and the liquids bromine and mercury.

['helium, at the top of group 0, has the lowest boiling point of any element.', 'boiling point increases going down the group.']

Amazingly almost every element can exist as a solid, a liquid, and a gas - it all depends on the temperature. Mercury, for example, is generally found as a liquid but at -40 degrees Celsius it freezes and turns into a solid. And Mercury vapor (gas) is found in some particles of light.

Characteristics: Mercury is a dense, silvery-white, poisonous metal with a mirror-like appearance. It is the only common metal that is liquid at room temperature. Mercury evaporates slowly at room temperature.

Metals are lustrous, malleable, ductile, good conductors of heat and electricity. Other properties include: State: Metals are solids at room temperature with the exception of mercury, which is liquid at room temperature (Gallium is liquid on hot days).
