Nitrogen - Periodic Table of Videos

TL;DR

Witness the fascinating properties of liquid nitrogen, from its strong bonds to its cool applications in laboratories.

Transcript

So we're gonna go find some liquid Nitrogen. We keep it in a really large dewar tank at the back of the shop, so we're gonna go find that now. So this is a dewar that we used to keep the liquid Nitrogen in within the building so it's much more convenient for us and our students to get it. So what we're gonna do now is we're gonna fill up our small... Read More

Key Insights

• 💪 Liquid Nitrogen has one of the strongest bonds between N2 atoms in the Periodic Table.
• 👻 Its low boiling point of -196 degrees Centigrade allows it to function as a coolant in laboratories.
• 👁️‍🗨️ Liquid Nitrogen demonstrates unique properties like freezing materials instantly and creating bubbles that clean dust.
• 🫀 The compound is used in explosives since isolated Nitrogen atoms release energy upon bonding during explosions.
• 🔬 It is favored in laboratories for its non-reactivity compared to Oxygen.
• 🥶 The cold properties of liquid Nitrogen can be used to freeze and reshape objects like lenses.
• 💁 Liquid Nitrogen can turn flexible materials like rubber into brittle forms that can easily shatter.

Questions & Answers

Q: What makes the bond between Nitrogen atoms unique?

The bond between N2 atoms is among the strongest in the Periodic Table, making it a stable and non-reactive compound.

Q: How is liquid Nitrogen used in laboratories?

Liquid Nitrogen is utilized as a coolant and to create an inert atmosphere for experiments, preventing unwanted reactions that may occur with air.

Q: What happens when materials like rubber are put into liquid Nitrogen?

Materials like rubber become extremely rigid and brittle when exposed to liquid Nitrogen, allowing them to shatter easily with force.

Q: How is liquid Nitrogen used humorously in practical jokes?

Liquid Nitrogen can be siphoned through tubing to freeze objects or even someone's legs, showcasing its versatility beyond scientific experiments.

Summary & Key Takeaways

• Liquid Nitrogen exists as N2 gas with one of the strongest bonds in the Periodic Table.

• Widely used in laboratories for its non-reactivity and as a coolant due to its extremely low boiling point.

• Demonstrates unique properties like freezing materials instantly and creating bubbles that clean dust.
