WebElemental 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).
WebRegular everyday metallic mercury is monoatomic Hg (0). Dissolved mercury (I) compounds are diamagnetic: Hg2 (2+). That is actually two mercury atoms that are bonded to each other. This is due to the 4f and 4s shell overlapping and some stuff to do with bond distances. There are also polymagnetic mercury compounds such as Hg3 (2+). slysoft anystreamWeb15 aug. 2024 · Characteristics: Mercury is one of the few liquid elements.
