Tungsten - Tales from the Periodic Table
Ғылым және технология
Tungsten is one of the densest element you are likely to encounter. Anything denser will be either extremely expensive, or dangerously radioactive. Indeed, the name "Tungsten" is derived from the Swedish for "Heavy Stone". It's density leads to its ability to block x-rays as you'll see in the video. It has one of the highest melting points of the elements and is therefore useful in anything that is involved in high temperatures - like a lightbulb filament. Tungsten is also a very hard element only surpassed by Chromium, Boron, and Carbon in the diamond state. Compounds such as Tungsten Carbide are even harder than the pure element and can be used for cutting tools. This is one of my favorite elements!

Thank you for shedding light on element 74. It must be hard to discuss such a heavy subject.

@@ronhipschman Yaaay, it's such a fascinating element, with what seems to be minute information about it. Especially the mining aspect. Looking forward to what you find out and present!
This one was really worth the weight.

@@ronhipschman Love it! One quibble: your narration is off by a century during the discovery chapter; those crazy cats were all dead by the 1870s! (Okay two quibbles: there's a typo in the slide on tungsten carbide.)
Since Carbon sublimes at atmospheric pressure, Tungsten is the element with the highest melting point under normal atmospheric pressure. Seems a little unfair to Carbon, which is solid to a higher temperature. If Tungsten darts are too cheap for anyone, they've also made them out of Rhenium, which makes Tungsten look positively common. I enjoyed this video. Tungsten is an element of extremes. Didn't know about the use in X-ray medicine.

The only "Rhenium" darts I could find were actually Tungsten darts with 5% Rhenium. I think only one company made them and they are heavily sought after, if I read my eBay properly. Ron

@@ronhipschman Those must be the ones. I would try plating them with Rhenium but it sounds like they use an alloy.
Apologies for the puns, admittedly they're a bit tungsten cheek

but how long is a half life
@ronhipschman

A half-life is the time it takes for 1/2 of the substance you have to decay. In the case of Uranium-238, it takes 4.5 billion years for 1/2 of any lump to decay, so the half-life id 4.5 billion years. Ron
this is surprisingly uniform distribution of natural occurring stable isotopes.
These vids are awesome, never stop making them
