Xenon (version 1) - Periodic Table of Videos

TL;DR

Xenon, a dense inert gas, sinks quickly, used in powerful lights and expensive lasers, derived from air separation.

Transcript

say in the balloon we've got a sample of xenon now Xenon's one of the inert gases but it's one of the inert gases just right the way down the bottom in the period so it's really really dense so what that means is that the gas molecules themselves are really really large really really heavy so in principle they'll sink so xenon is one of my favorite...

Questions & Answers

Q: Why is xenon considered a dense element?

Xenon is dense due to its position at the bottom of the periodic table, with heavy and large gas molecules, causing it to sink rapidly.

Q: How is xenon utilized in lamps and lasers?

Xenon is used in xenon lamps for powerful light emission and in lasers for applications like military spotlights and Reagan's Star Wars program.

Q: Why did the price of xenon increase in the 1980s?

Xenon's price surged in the 1980s due to increased demand for lasers, leading to limited supply as xenon is derived from air, impacting research affordability.

Q: How is xenon extracted during air separation?

Xenon is separated from air during air liquefaction after nitrogen and oxygen extraction, leaving behind noble gases like argon, krypton, and xenon.

Summary & Key Takeaways

• Xenon is a dense inert gas found at the bottom of the periodic table, making it heavy and large in molecule size.

• It can be liquefied easily, used in xenon lamps for bright light output and in powerful lasers.

• Xenon's price hike due to demand, industrial downturn impacted its availability from air separation.
