The 5 Most Dangerous Chemicals on Earth

Can you imagine a substance so deadly that even a millionth of a gram could kill you? They explode when you touch them. They can even disable you with their horrifying smell. Join Hank Green for a new terrifying episode of SciShow that will introduce you to the most dangerous chemicals in the world.

What keeps me up at night is that... how toxic it is when inhaled. So... "described as" is more like "uttered by a dying man". Now Im wondering how that being overcome by the elements would look like.

What keeps me up at night is that scientists tested all these toxic chemicals on animals. They test any toxic chemical they can find on them. I think about it all day everyday...

People used to be a bit careful about click chemistry (the azide-alkyne cycloaddition type) because of what was called azidophobia. No-one wanted to mess with explosive nitrogen compounds 😂 I've worked with them a lot, the general rule is to have a lot more carbons than nitrogens and then they tend to play nice 😊

[@itsme5625]

Is one of the way to determine is it safe to isolate/store is to take the ratio of nitrogen/carbon If its below 1 it will blow up if isolated or concentrated, 1-3 is alright but shount be stored for long, and above 3 is safe to do anything with it.

Yeah, oxidation is a strange relic of a name. Chemists used to believe oxygen was THE oxidizer, until they realized _why_ oxygen works the way it does(it loves to steal electrons), and so they learned there were other compounds that could be used to 'steal' electrons as well, but they still kept calling it "Oxidation". I propose we start calling it "Electrokleption", literally "electron stealing".

This was one of the first scishow videos I ever watched! 8 years later and I’m still here thanks to this wild video!

[@jamierichardson9981]

Spot on with your explanations. I now run a daycare (Which has its own toxins), but I used to be a chemist and I worked with variations on just about everything you talked about. The first company I worked for made antimony products including catalysts and other much more tame products. The second company I worked for made fluoridated polymers and the gases that go into them. The statement about how aggressive fluorine is in attacking your body is absolutely true. And let's just say that any metal can get excited under the right conditions. Not for the faint of heart, or the careless.

Wonderful. I enjoyed this just as much as Hank seemed to! I worked as a truck driver for a chemical company once, and one time I had to deliver a load of Hydrofluoric Acid. I was given a Rubber Apron, Rubber Boots, Rubber Gloves and a mask, and still they warned me to be absolutely sure not to spill any. Scared the crap out of me!

Except you can hit it with a hammer and it doesn't actually explode. It's not that it was super sensitive. It's that they didn't have the equipment required to test sensitivity.

Following in the steps of Haystack last year, I am happy to report that it is the tail end of 2022, and this still remains one of the best SciShow videos of all. It's obvious you enjoyed making it as much as all of us did watching it. But I just gotta ask: Why do you pronounce "antimony" differently than does Tom Lehrer in his classic song, "The Elements"? It would be heresy to think Lehrer might have been WRONG - horror of horrors!!!!!

if you talk in class with others that your teacher is stupid instead of learning, then you are dumb.if you are learning in class, then you most likely should be doing good at school. you should be doing homework too, dont blame the teachers for teaching you badly or something, blame yourself for not paying attention.

[@Nick-tm2sw]

Although from a physics perspective it wasn't nothing that caused it to explode. It gets into statistical thermodynamics to explain further but there was something happening that caused the explosion. Just not any type of external force. The energy that caused the explosion would have already been in the system. They could have likely prevented the explosion by storing it at a cooler temperature.
