Mercury is the only elemental metal that is liquid at ordinary temperatures (cesium melts at about 28.5° C [83° F], gallium at about 30° C [86° F], and rubidium at about 39° C [102° F]). Mercury is silvery white, slowly tarnishes in moist air, freezes into a soft solid like tin or lead at about -39° C (-38° F), and alloys with most metals (iron is a notable exception) to form amalgams. Mercury does not wet glass or cling to it, and this property, coupled with its uniform volume expansion throughout its liquid range, makes it useful in thermometers. Barometers and manometers utilize its high density and low vapour pressure. The good electrical conductivity of mercury makes it exceptionally useful in sealed electrical switches and relays. An electrical discharge through mercury vapour produces a bluish glow rich in ultraviolet light, a phenomenon exploited in ultraviolet, fluorescent, and high-pressure mercury-vapour lamps. Mercury's high thermal neutron-capture cross section (360 barns) and good thermal conductivity make it applicable as a shield and coolant in nuclear reactors. Much mercury is utilized in the preparation of pharmaceuticals, agricultural and industrial fungicides, as dental fillings, and in the electrolytic production of chlorine and caustic soda.

Hg, mercury is the only metal to be liquid at room temperature, ie 25 degrees C. Ga, Gallium is liquid at body temperature or slightly above room temperature appx 30 degrees as it will melt in your hand. Br, Bromine is a liquid at room temperature but it is a nonmetal.

Bromine (symbol Br and atomic number 35) and mercury (symbol Hg and atomic number 80) are both liquids at room temperature. Bromine is a reddish-brown liquid, with a melting point of 265.9 K. Mercury is a toxic shiny silvery metal, with a melting point of 234.32 K.

Mercury(Hg) and Gallium(Ga). That makes 2! (Bromine is a non-metal)
