xenon
Let an agent explain xenon as an element, relay its properties, isotopes, uses and handling information from reference sources, and separate it from other noble gases and from its compounds.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain xenon as an element, relay its properties, isotopes, uses and handling information from reference sources, and separate it from other noble gases and from its compounds.
A colourless, dense noble gas, chemical element 54, present in trace amounts in the atmosphere and obtained by fractional distillation of liquid air; used in high-intensity lamps, ion propulsion for spacecraft, medical imaging and anaesthesia, and in physics experiments as a detector medium, with many stable and radioactive isotopes.
What it is for: Lighting, ion propulsion, anaesthesia, imaging and detectors.
It can be explain properties and isotopes; explain uses and how it is obtained; relay handling and safety information; distinguish it from other noble gases.
Distinguishing features
Noble gas, but forms compounds with fluorine and oxygen
Heaviest stable noble gas
Anaesthetic properties
Many isotopes used in research and medicine
What it looks like
Colourless, odourless gas; glows blue in electric discharge.
Physical character
atomic number: 54
boiling point: about -108 degrees C
atmospheric abundance: about 0.09 parts per million by volume
stable isotopes: 7 isotopes - plus two very long-lived
