Only two elements are liquid at room temperature (around 20°C or 68°F):

* Mercury (Hg)

* Bromine (Br)

It's worth noting that gallium (Ga) is also a liquid at room temperature, but only slightly above it (around 29.76°C or 85.57°F). So, it's considered to be a solid at standard room temperature but is often included in this list.
