Elemental mercury, a liquid at room temperature, is 13 times denser than water. Enough it turns out to support a man of average build and yes, if you type man sitting on mercury into Google, you'll quickly find a 1972 photograph, published in National Geographic of a man suited and booted, sat unaided, albeit a little nervously, on top of a ...
Elemental mercury (‘quicksilver’), when ingested, is poorly absorbed from the gastrointestinal tract and poses few toxic consequences. Metallic mercury, however, is very volatile and vaporizes readily. Mercury vapor, when inhaled, is absorbed efficiently (Berlin et al. 1969) and has a high affinity for the central nervous system (CNS).
Mercury (Hg) is a heavy silvery-white metal that is found in liquid state at room temperature. It is also known as quicksilver or hydrargyrum. Mercury with atomic number 80 has many characteristic features. It is the only metal that is liquid at standard conditions for temperature and pressure. [ 1]
