Like all noble gases, xenon is colourless, odourless and inflammable — but it is also more reactive, and much rarer, than its lighter relatives. Ivan Dmochowski ponders how xenon, though ...

Noble gases are especially helpful for deep-time investigations because they are chemically inert. Some of their isotopes were trapped in the interior 4.5 billion years ago when the Earth first ...

Solid Noble Gases The simplest systems available for the study of a wide range of solid-state phenomena may be the crystal structures that are formed at very low temperatures by noble-gas atoms By ...

The IAEA offers a variety of training courses in the fundamentals of isotope hydrology and isotopic analyses of stable isotopes, tritium, and noble gases. This course provides an overview of advances ...

The hot metal wires will burn away if any oxygen from air is present in the lamp. Argon, krypton and xenon are very unreactive. They replace the air inside the lamp, preventing the metal wire from ...

The actual boiling point of radon is -61.7˚C. An estimate would lie midway between -100˚C and -50˚C based on the shape of the graph.
