Mercury (Hg) is the only metallic liquid element at room temperature
and Bromine (Br) is the only non metallic liquid element at room temperature.
The melting point of Bromine is -7.2 C and mercury has a melting point of -39 C.
Despite other answers Barium is definitely not a liquid at 20C it has a melting point of 727 C.

Look at a color coded periodic table. Color codes will list the matter state at room conditions:
For example, use this one:

You will find that Br and Hg are your answers.
With the above table in hand you will be able to answer which ones are gases.

mercury. barium and mm, hydrogen and oxygen, at 20c water is pretty soluble. most compressed gasses become liquid... argon, hydrogen,oxygen and helium (the list goes on) check the periodoic table, and find out how pedantic you can be...
