Out of all the known elements, which has the greatest density?

"Osmium metal, the densest element, has a density of 22.5 g/mL" http://129.93.84.115/Chemistry/DoChem/DoChem011.html Apparently Indium is very nearly as dense. Oct 08 03, 11:16 AM

Researchers have recently discovered the heaviest and densest element known to science: Administratium. Administratium has one neutron, 12 assistant neutrons, 75 deputy neutrons, and 111 assistant deputy neutrons, thereby giving it an atomic mass of 312. These 312 particles are held together by a force called morons, which are surrounded by vast quantities of particles called peons. Since Administratium has no electrons, it is inert. However, it can be detected because it impedes every reaction with which it comes into contact. A minute amount of Administratium causes one reaction to take more than four days to complete when it would normally take less than one minute. Administratium has a normal half-life of three years. It does not decay but, instead, undergoes a reorganization, in which a number of the assistant neutrons and deputy neutrons and assistant deputy neutrons exchange places. In fact, Administratium's mass will actually increase over time, since each reorganization causes some morons to become neutrons....forming new isodopes. This characteristic of moron transformation leads some scientists to speculate that Administratium is formed whenever morons reach a certain quantity in concentration. This hypothetical quantity is referred to as "critical morass". You will know it when you see it. Oct 08 03, 11:18 AM

Unfortunately, the researchers who discovered Administratium were shortly thereafter smothered under an unexpected avalanche of paper. Oct 08 03, 12:06 PM

Riotgrrl is right about osmium (sometimes used in quality pen-nibs and whose name comes from the Greek "smelly") but indium is not nearly as dense. I guess you meant iridium, which is. Oct 09 03, 8:09 PM
