The metal with the lowest melting point is mercury, which melts at -38.83 degrees Celsius (-37.89 degrees Fahrenheit). This unique property makes mercury different from most metals, as it remains liquid at room temperature.
Mercury’s low melting point is due to its atomic structure and the weak metallic bonds between its atoms. When compared to other metals, such as iron or aluminum, which have much higher melting points, mercury stands out as an exception in the category of metallic elements. Because of its liquid state at normal temperatures, mercury has been used in thermometers and barometers for many years, although its use has decreased due to toxicity concerns.
