Krypton will form fluorides at the temperature of liquid nitrogen, but these break up slowly at room temperature. Of xenon, a variety of fluorides and oxides and oxyacids can be made. Radon reacts even more readily, but with a radioactive halflife of only c.4 days, there is not much a chemist can do with it. The next noble gas would be element 118 (ununoctium, eka-radon), and if it existed in nature in quantity it would likely be not as a gas but as a stable oxide mineral. And with bacteria in the body, some time the body's immune mechanism will try to kill them, same as with ordinary disease bacteria. In reverse, I suppose that one reason why people and animals are not "azototelic" (i.e. turning waste amino nitrogen (from proteins in food) into nitrogen gas) is that it would give the animal bends. One of my ultimate diving equipment daydream would be a UK naval type frogman's type oxygen rebreather plus a reliable medication to prevent oxygen poisoning down to say 7 bars = c.200 feet. OK, oxygen bends are known, but the body would consume it and not let it hang about. Does anyone out there know the medical outcome of known cases of oxygen bends? -- Send mail for the `techdiver' mailing list to `techdiver@aquanaut.com'.
