Bromine (Br) and Mercury (Hg) are the only two liquid elements on the Periodic Table. (at room temperature and normal pressure that is)
One unusual aspect of bromine is that it is the only non-metallic element that is liquid at room temperature. Additionally, bromine is one of the few elements that can exist in all three common states of matter (solid, liquid, and gas) at normal atmospheric pressure. Bromine's properties make it unique compared to many other elements in the periodic table.
The only liquid elements at room temperature (on the periodic table) are Mercury and Bromine.(Check the related link for a dynamic periodic table which shows the state of each element at various temperatures.)
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.
Atoms of all elements exist in the state of matter known as the gas phase.
Gases may be elements, compounds, or mixtures. A gas is a phase state of matter.
Mercury's state of matter is a liquid. Mercury is not a good conductor of heat and cinnabar is the largest natural source for mercury.
Most elements are solids when they are at very low temperatures.

Hg is the only liquid metal at room temperature, melting point 234.32 K, (-38.83 °C, -37.89 °F)Together with Bromine it is one of the only two liquid elements, all others are solid and only some (11) are gaseous.
At standard temperature and pressure (25 Celcius and 1 Atmosphere) it will be a liquid. Below -7.2 °C it will be solid Above 58.8 °C it will be a gas (Again assuming standard pressure of 1 Atmosphere)
Bromine is in liquid phase at room temperature.
