gas
From our reading in Disappearing Spoon we discovered that there are only 2 elements that are liquid at room temperature on the periodic table. One of them was element 35, Bromine. The other one is poisonous but we only more recently found out about that. It used to be sold to help stomach issues and has been used in measuring instruments for pressure and temperature in the atmosphere.
