Caesium melts at 28 degrees Celsius, just slightly above room temperature ("room temperature" in chemistry is pretty commonly taken as 25 degrees Celcius, which is actually somewhat on the warm side, and most people would be more comfortable at 23 or so). It would melt readily in your hand (normal human body temperature is 37 degrees Celsius), though touching caesium would be an exceptionally bad idea because it is highly reactive.
Gallium melts at just under 30 degrees Celsius, and would likewise melt in your hand, a safer demonstration since it's much less reactive.
In addition, francium probably has a melting point of about 27 degrees Celsius, though it's hard to tell for sure since the largest amount of Francium ever collected together in one place was a few hundred thousand atoms... about a third of a trillionth of a gram.
On the low side (elements that are liquid, but close to their freezing point at room temperature), the closest is bromine, which melts at -7 degrees Celsius... fairly cold, but not remarkably so in many places in the US during the winter months.

What do boiling point and melting point have to do with the phase of matter of an element at room temperature?
The state of matter of a substance at room temperature depends on whether the melting and boiling points are above or below room temperature. At room temperature:A substance is solid if both the melting and boiling points are above room temperature.A substance is liquid if the melting point is below room temperature but the boiling point is above room temperature.A substance is a gas if both the melting point and boiling point are below room temperature.
What is the only metal that's not a solid at room temperature?
Mercury is Classified as a Metal in the periodic Table, however it is liquid at room TemperatureMercury is not solid at room temperature.mercury is liquid at room temperatureWell, of the elements there are a few, actually.mercury, melting point −38.72 °Cfrancium, melting point 27 °Ccesium, melting point 28.55 °Cgallium, melting point 29.76 °C... hotter than that, and it is not a room I would want to spend much time in. Rubidium, potassium, and sodium all melt below the boiling point of water.Alloys of low-melting point elements melt at room temperature or below.mercury
Do solids have a low melting point?
Some do while others do not. To be solid a substance must merely have a melting point that is above room temperature. Gallium has a melting point just above room temperature, so it is normally solid but it will melt in the palm of your hand. By contrast Tungsten has such a high melting point that not even the hottest lava from Earth's volcanoes can come close to melting it.
Why Iodine melting point is above room temperature?
Iodine melting point is above room temperature because its vapor pressure is less than one atmosphere.
Is oil solid liquid gas?
liquid. think of what you put into your car.
Why is Mercury used in thermameter?
Mercury's melting point is close to the room temperature, so it is a good indicator of temperature around room temperature.
How can you determine if a substances is a solid at room temperature?
Check the melting point of the substance. If the melting point is below room temperature, then the substance is liquid and if the melting point is above room temperature then it is solid.

Is diphenylmethane solid at room temperature?
The melting point of diphenyl (Biphenyl) is 156.6 degrees Fahrenheit, so it is a solid at room temperature. Acetone has a melting point of -139 degrees Fahrenheit, so it is a liquid at room temperature.

What is the temperature of copper at room temperature?
As to the room temperature of copper, your question isn't exactly making sense, because to me the copper would be the same (or close to) the temperature of the room. But if you were looking for this other info, here it is: Copper (Cu) Melting point: 1984.32 °F Boiling Point: 4643 °F
Almirah is solid at room temperatures give two reasons?
Almirah is a solid at room temperature, because it will only be liquid at its melting point and the room temperature is not its melting point.
What are 5 liquids that do not have water?
-- pure alcohol at room temperature -- mercury at room temperature -- oxygen below its boiling temperature -- iron above its melting temperature -- nitrogen below its boiling temperature -- salt above its melting temperature -- gold above its melting temperature -- any other element or compound that is not H2O, above its melting temperature and below its boiling temperature
Are most elements a solid liquid or gas at a room temperature?
most of the elements are solids at room temperature.
At what state are most elements at room temperature?
On the Periodic Table, the majority of elements are metals and some of elements are non-metals . Most metals have a high melting point which means therefore the answer to this question is solid.
Are all elements are solids at room temperature?
no not all metallic are solid at room temperature.
