At room temperature, the only liquid metal element is mercury. Mercury is a unique element that remains in a liquid state at normal room temperatures due to its low melting point of -38.83 degrees Celsius (-37.89 degrees Fahrenheit).

Mercury is a silvery, heavy metal that has been used for various purposes throughout history, including in thermometers, barometers, and electrical switches. However, due to its toxic properties, the use of mercury has become more regulated in recent years.

Despite its toxicity, mercury has some interesting properties that make it useful in certain applications. For example, mercury is a good conductor of electricity and is often used in electrical switches and relays. It is also used in some types of batteries and fluorescent lights.

If you are interested in learning more about mercury and its properties, you can visit the website of the Royal Society of Chemistry. They provide detailed information about mercury, including its atomic structure, physical and chemical properties, and its uses in various industries.

Overall, mercury is a fascinating element that defies the norm by remaining in a liquid state at room temperature. It is important to handle mercury with care due to its toxic nature, but it can also be an essential element in certain applications where its unique properties are needed.

For more information on liquid metal elements and their properties, you can also check out the Encyclopedia Britannica. They have a wealth of information on various elements, including mercury, and how they behave in different states.
