Caesium or Cesium (version 1) - Periodic Table of Videos

TL;DR

Cesium, a reactive metal, has unique properties such as being both solid and liquid, making it dangerous to handle.

Transcript

so cesium it's a very reactive alkaline metal sort of getting on down in the periodic table you got to be very careful with season it's very very reactive it's very very expensive as well and when you're trying to buy it you got to be very careful because there's a couple of different spellings you see on our box here we got cesium with an a cesium...

Key Insights

• 🤘 Cesium is a reactive alkaline metal often spelled with or without an "a."
• 🫗 The physical state of cesium can vary from solid to liquid depending on temperature.
• 👱 Cesium is handled with caution due to its reactivity with moisture and air.
• 🫀 The large atoms of cesium contribute to unique properties like bendability in cesium bromide.
• 🙂 Cesium is valued for its infrared light transmission capabilities.
• 🍵 Handling cesium requires careful measures to prevent hazardous reactions.
• ✋ Cesium's rarity and unique properties contribute to its high cost.

Questions & Answers

Q: Why is handling cesium considered dangerous?

Handling cesium is dangerous due to its reactivity with moisture and air, leading to an exothermic reaction. Even perspiration can trigger a vigorous and potentially hazardous chemical reaction.

Q: What makes cesium unique in terms of its physical state?

Cesium can be found in both solid and liquid states, depending on its temperature. With a low melting point close to room temperature, cesium can transition between states easily.

Q: Why is cesium worth a significant amount of money?

Cesium is expensive due to its rarity and unique properties, making it valuable in various scientific applications, such as its use in infrared light transmission in cesium bromide.

Q: What are the distinguishing properties of cesium bromide?

Cesium bromide's ability to transmit infrared light effectively is attributed to the large size of both cesium and bromine atoms, allowing for slow vibrations that do not strongly absorb infrared light.

Summary & Key Takeaways

• Cesium is a reactive alkaline metal often spelled with or without an "a," uniquely found as both solid and liquid depending on temperature.

• Handling cesium requires caution due to its reactivity with moisture and air, making it potentially dangerous if mishandled.

• Cesium's large atoms contribute to its unique properties, like bendability in cesium bromide, valued for its infrared light transmission.
