What is Xenon?

Xenon is a rare, heavy, colourless noble gas. Despite its reputation as completely inert, xenon forms compounds with fluorine and oxygen. It is obtained commercially from liquid air by fractional distillation.

Formula & Notation

Xe

Properties & Characteristics

Appearance: colourless gas. Melting point: −111.75 °C. Boiling point: −108.12 °C. Density (gas): 5.894 g/L. Solubility in water: 108.1 mL/L at 20 °C.

Uses & Applications

High-intensity arc lamps (cinema projectors, car headlights). Flash lamps in photography. Ion propulsion in spacecraft (ion drive). General anaesthetic at high pressures. NMR spectroscopy (Xe-129). Nuclear physics research. Xenon-133 for lung ventilation imaging.

Safety Information

Non-toxic and non-flammable. Asphyxiant in high concentrations. At high pressures acts as a general anaesthetic; anaesthetic effect is irreversible at extreme pressures. Generally considered one of the safest gases to handle.

Always consult the SDS/MSDS before handling any chemical. This information is for educational purposes only.
