TL;DR

Tungsten, a dense metal, has various uses in everyday life and can be experimented with in exciting ways.

Transcript

today we're going to talk about tungsten we spent a long time preparing and so there's a lot to show you there are things that didn't work there are some really spectacular experiments and some of them we've invented ourselves don't think they've been filmed before tungsten is the element in group six low down in group six and it is very dense meta...

Questions & Answers

Q: What are some everyday uses of tungsten?

Tungsten is used in phone vibrating elements, barrow tips, and various other items due to its density and weight.

Q: Why does tungsten sink in mercury but floats in meibum?

Tungsten sinks in mercury due to its higher density, but when placed in meibum, which has a lower density than tungsten, it can float due to the buoyancy effect.

Q: What happens when tungsten reacts with sodium?

When tungsten reacts with sodium, it can form a solid compound known as tungsten bronze, and the amount of sodium used can produce different colors.

Q: How does tungsten react with bromine?

When tungsten is heated in bromine, a reaction occurs that results in the formation of bromides of tungsten, possibly tungsten tribromide.

Summary & Key Takeaways

• Tungsten is a dense metal in Group 6 of the periodic table with a high density and small size. It is commonly used in everyday items like phone vibrating elements and barrow tips.

• Tungsten can be used to demonstrate density differences, as shown through experiments with mercury and other metals.

• Chemical reactions involving tungsten, such as reactions with sodium and bromine, can lead to interesting results.
