বিষয়ে Xenon
Xenon is a dense, odorless noble gas found in trace amounts in the atmosphere. It was the first noble gas to form true chemical compounds in 1962. Despite its rarity, xenon has many applications.
Uses & Applications
Ion propulsion engines, high-intensity arc lamps, medical anesthesia, and HID xenon headlights.
মজা কথা
Xenon was the first noble gas proven to form compounds in 1962, shattering the assumption that noble gases never react.
