Xenon

Xenon is a colorless, odorless gas found in trace amounts in the Earth’s atmosphere. It is one of the noble gases, which means it is chemically inert and doesn’t easily react with other elements. Xenon is used in various applications, including lighting (such as high-intensity discharge lamps and flash bulbs), medical imaging (in some types of CT scans), and in some types of ion propulsion systems for spacecraft. Due to its rarity and unique properties, xenon is also of interest in scientific research and experiments.
