Best exposition of Beryllium ever!

[@omsingharjit]

How it is possible , to be both lighter and denser and harder without reducing its volume at same time ?? I mean if denser means its atoms are closer With others so it should take less volume then other elements like iron ????

[@chemistryscuriosities]

I’m pretty sure the golden colored beryl is called Heliodor. From Wikipedia : Heliodor is the beryl variety that receives its yellow color from Fe3+ ions. The name "heliodor" originated as a trade name for golden beryl from Rössing, Namibia but now encompasses any gem-quality, golden-yellow beryl. Heliodor, Brazil.

this video was so much fun to watch. thank you for posting it. I initially searched the term beryllium because I've recently noticed its use in a hobby of mine: the audio world. a company started using beryllium to make small dynamic drivers to go inside earphones. after watching this video, I understand why due to its rigidness and how fast sound travels through or across it.

[@arronsondrini380]

Ha I am watching because the tweeters in my Focal studio monitors are beryllium. There awesome :)

[@bernardputersznit64]

Marvelous tour - thank you.

[@imme9927]

Thanks, got precise knowledge on beryllium

[@michaelbayer5887]

... Beryllium ist a moderator - and in it also hidden Numbers 137 of mathematics in Barium Atom Mass 137 and Cäsium 137 - its fine dust number - so by big bang the Explosion and Expansion becomes slowlier and slowlier - but never Stop - it is just the critical expansion by using Beryllium as Reflektor.

[@zenjon7892]

...why is he and the audience handling the metal with bare hands? Also, that's a valuable piece of beryllium!

[@HighlanderNorth1]

**Because it's only toxic in fine, powdered form if you breath it into your lungs over a period of time. Holding a smooth, solid chunk of beryllium metal is no more poisonous than wearing emerald or aquamarine jewelry.**

[@robertgardner7470]

SF200 beryllium contains about 2% BeO impurity and is stronger than steel. It has extreme hardness. Unless ultra pure (.999) it cannot be sawed , milled or drilled. Grinding beryllium would be very hazardous causing dust which could be accidentally inhaled.

[@aristeidislykas7163]

You did not mention that beryllium is used for making diaphragms for speakers.

[@deaftodd]

That's a good video!

[@HeathenHammer80]

I’m confused on the density. Why is he remarking on how light it is? If water has one gram per cubic centimeter of mass and beryllium has 1.85 gm/cm3, isn’t that more dense? Wouldn’t that make the beryllium heavier if you compare it to the same volume of water?

[@erickiplimo]

Won't you get berylliosis from touching beryllium?

[@NinoNiemanThe1st]

No, the pure metal is reasonably safe. Just don't cut it and get any dust from it.

[@jonathanbell9349]

I found a small chunk of beryllium and it has given me strange powers....

[@zapfanzapfan]

Cool!

[@bimmjim]

*I did not know that*

[@jimjardine4705]

Where do you find it?

[@monarchatto6095]

Jim Jardine eBay ebid or Amazon,mine was ebid and my red beryll is 69$

[@hassankhatar8060]

I have stone 400 g 00963945433653

[@nataliap2705]

It's not "Columbia"... It's Colombia with an "o". One of you slides had that mistake. Very interesting. Would like to know what atomically properties makes Be so smooth? Or maybe that is too complex for the layman. Anyways, wonderful!

[@bruce122046]

Be is toxic I've been told, So how are you able to pass several chunks of Be metal around the room?

[@bingosunnoon9341]

Stupid is my guess

[@lbride3738]

If it is pure Beryllium, I won't hold it unless under gun point. The cube must be Be alloy.

[@NinoNiemanThe1st]

You're confusing pure beryllium metal with its highly toxic powdered forms if they are absorbed (pure Be or oxides etc.). On its own, pure beryllium metal is quite safe to handle, though yes, I'd prefer to stay away from it all together. Absorbed beryllium (in powder forms) causes subtle, long-term BIG problems to humans. It's such a tiny atom that it just 'gets in' and causes dangerous chronic inflammatory reactions. That cube of pure Be must be worth at least a few thousand dollars. It's hard to machine and mostly used these days for X-ray windows as it lets them through.

[@nocturnalknight2580]

wow didnt even cover red beryl

[@kevi152]

No panthers in Brasil ! Jaguar perhaps .

[@Jaburu]

about 4 times as big? looks more like 100-times-ish lol

[@theq4602]

Just got myself a large 135 gram sample of the stuff.

[@monarchatto6095]

I’m actually buying red beryll

[@theopinion367]

Be sound travel fastest sweet taste toxic uses transparent tube in x-ray. Beryllium laser gemstone emerald

[@chancebutler6472]

lol hidden double meaning of the beryllium sphere from an *airplane* being "one of the smoothest things" cause theyre also hiding anti gravity properties of gyroscopes

[@KuznVinny]

Too much introduction. Otherwise, very enjoyable.

[@chancebutler6472]

lol 13k views. might be too late now but i wish folks would wake up.

[@chancebutler6472]

(tyvm great video!)

[@johnnycash4034]

What do you mean by that?

[@bavarianmonkey8326]

And it is carcinogenic...

[@ivt8061]

the Be dust is only...

[@robertgardner7470]

It is not known to cause cancer. Workers exposed to Be fumes or dust can and sometimes do suffer from some degree of chronic lung inflammation. Beryliosis that has progressed to granulomatous pneumonitis can be treated with glucorticoids and immunosuppressive drugs to lesson symptoms. Only a small percentage of beryllium workers are affected by beryliosis. Every time you handle most metals a few atoms rub off onto your skin. It is hazardous to handle beryllium if you have a cut to your skin. Beryllium has a sweet taste and oral ingestion has not caused any ill effects.

[@Paul-kd3ui]

Carcino genic? So it's Italian haha you should be the real one

[@paulgaier4525]

Say their names.
