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 is the physical state of tungsten at room temperature?
SolidTin is solid at room temperature.
What elements is a liquid at room temperature?
Mercury and bromine are the only two elements liquid at room temperature.
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.

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 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 do you know the phase of matter for each element?
The phase of matter for each element can be determined based on its melting point and boiling point. Elements with low melting and boiling points, such as hydrogen and helium, are typically gases at room temperature. Elements with higher melting and boiling points, such as iron and aluminum, are typically solids at room temperature. Elements that are in between, like mercury, can be liquids at 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 bromine a gas at room temperature?
No, in its native, room temperature state it is a liquid , one of the 2 elements (Mercury being the other ) to be liquid at room temperature.

What is the temperature of platinum at room temperature?
The melting point of platinum is 1768 degrees Celsius, which is much higher than room temperature. At room temperature, platinum would be solid and not at its melting point.
What state is bromine at rom temperature?
Bromine is a liquid at room temperature. There are only two elements that are liquid in room temperature. The other one is Mercury.

What elements have the lowest boiling and melting points?
The noble gases, such as helium and neon, have the lowest boiling and melting points among the elements. These elements are gases at room temperature and have very weak interatomic forces that require little energy to separate them into individual atoms.
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.
