At room temperature (around 20-25°C), the only elements that naturally exist as liquids are mercury (Hg) and bromine (Br). Mercury is the only metal that is liquid at this temperature, while bromine is a halogen nonmetal that appears as a reddish-brown liquid. Other elements like gallium, cesium, rubidium, and francium have melting points slightly above room temperature, so they are solid at typical room temperature but may become liquid just above it.
Summary of liquids at room temperature:
- Mercury (metal)
- Bromine (nonmetal, halogen)
Elements liquid slightly above room temperature:
- Gallium
- Cesium
- Rubidium
- Francium (rare and radioactive)
This is because most elements have melting points above or below this range, making liquids at room temperature quite rare.
