Recovering the cesium is possible and worthwhile, and required by law in most places since one is not allowed to dispose of cesium down the drain. Since almost all cesium salts are soluble, it's probably easiest to evaporate off the water (any combination of heat and vacuum) and collect the salt that remains. It might be best to start by neutralizing by bubbling in plenty of carbon dioxide, and then collect the dry carbonate salt. A less convenient way to neutralize is with a mineral acid and collect the salt (chloride, sulfate, nitrate, phosphate etc depending on the acid used). The advantage of using CO2 is that one does not need to use an exact quantity of it since it will leave no residue when evaporated. Once the salt is collected, it can be sold or passed to specialist labs that extract the metal, which, in the case of cesium, is almost impossible in a conventional lab without special equipment

The combination of more Coulombic attraction and heavier electrons means the outer shell electron of Francium has a higher ionization energy than expected.

⁠@@deusexaetherabecause francium is a heavier element, it’s more positively charged for its size compared to elements like cesium or potassium.

Man I love your channel; each post is so appreciated! Thank you dude.

Glad to see the coulombic explosion explanation is spreading. I would say the way Cesium reacts with the water comes from it having a low enough melting point to get an instant explosion in a room temperature experiment, unlike Sodium and Potassium which need to melt first (NaK shows the ability for instant explosion probably due to its liquid state at room temp). Being a liquid reduces the interference from surface oxides as they slough off, and also permits the surface to change as is necessary for the coulombic explosion. Seems like the gas layer created by sodium and potassium delays the explosion which is why you can see them melt before exploding.

Is it just me or have your experiments been way more intense lately? 😂 Not complaining haha

cesium is actually a solid under ambient conditions, so unless you heated it with your hands to melt it (ca 28 °C), your sample very likely contained some other (earth) alkali metals as impurities stemming from the synthesis of the cesium

One of the greatest and most memorable experiences of my life was given to me by an educator. I'll be vague as he isn't dead yet. He was very creative in his methods. He introduced a handful of us to the reactivity of sodium by chucking a large block of it into a small body of water. It exploded quite a few times. The chunk didn't come apart for a bit and the explosions were enough to heave it out of the water while it was still one piece. I chose "heave" on purpose as it was more of a riding the wave scenario, but it would leave the surface of the water and travel a bit. They would put him in jail today, but I retained everything he ever tried to teach me.

Cesium-137 is an isotope, whereas the cesium he is handling is the normal element.

Cesium-137 is an isotope with an atomic mass of 137 compared to the normal 135 of non-altered cesium. Because of this difference, some isotopes are radioactive (wildly so in the case of cesium-137).

@@MatteoCampinoti94 the only thing I would add to help connect dots for the OP is that the smaller number of neutrons in the highly-radioactive cesium 135 means there's an imbalance between the forces keeping the nucleus together and the interior repulsive forces of the protons pushing against each other. That's what makes it unstable and so happy to split apart in radioactive decay.

My high school chemistry teacher (who was highly overqualified for his job, having a doctorate, many published scholarly papers, etc.) told a story about his younger days in Amsterdam (he was dutch with an accent that went perfectly with the "chemistry professor" gig) when his lab group were moving from one building to another, and they had a big hunk of potassium that they just dropped in a canal. It sank to the bottom and they just sat there and watched because it wasn't reacting, wasn't reacting, wasn't reacting... and then as a gondola approached it, went off like a depth charge with flame and smoke and all that good stuff. Of course, the gondolier had no idea what was going on, and crashed the gondola into the side of the canal trying to avoid the explosion. (But of course, it was going slowly, leisurely, so nobody was hurt.)

Anyway be it 0°C, or 20°C or even 25°C Cesium is solid at those temperatures.

I work in the Oil and Gas industry; when drilling extremely high-pressure formations, we use Cesium Formate as the drilling mud to counter the pressures. My question is, how is the Cesium stabilized? An interesting fact about the Cesium Formate is that you can't buy it; you must rent it. For offshore jobs, a boat pulls alongside and delivers it to the rig. The ship stays until the job is done, and you must pump it back to the ship. As you can imagine, it is a costly operation. Rough numbers - Gulf of Mexico Sea Water is about 9 pounds per gallon. Cesium Formate is in the 20 pounds per gallon range.

Someone, get this man a new cesium sample; he deserves it.

Technically speaking the lighter the atom the more energy is released in that reaction, with lithium being the highest and cesium (discounting francium which you will never be able to test) being the lowest.

If you melted the sodium/potassium before letting it out underwater would it be able to react in a similar instantaneous manner to cesium? My logic goes that pressure from the hydrogen gas would quickly rip the blob of sodium into tiny droplets with much higher surface area and thus force them to react quicker, as opposed to with a solid hunk, which only can react a little bit at a time at the very outside and has time to float to the top before doing anything drastic.

The answer lies in Mr. Bernoulli's explanation of pressures in moving systems. The total pressure is the sum of a static pressure and a dynamic pressure. You can experience this very easily when you hold two sheets of paper at finger's distance and blow air from your lungs between them. You might expect the papers to move away from each other because you add air and pressure in the room between them. The opposite is true. You replace a part of the static pressure between them with dynamic pressure that has a specific direction, so the static pressure on the outside is greater and pushes the papers together. It's the working principle of injector pumps, carburetors and aircraft wings.

A Cesium additive was used in the jet fuel of the Blackbird spy plane that ionize in the exhaust stream to scramble enemy heat sensors from detecting the aircraft giant afterburners. It would be interesting to see your experiment using kerosene instead of water.

I love the videos! This man is way smarter than I could ever hope to be, but the way he pronounced "Jojoba" has me dyin XD

What i love about this is that i have no profesional formation of quimestry but the moment he says "electrons" I guess "he gon say hydrogen" it's satisfying af 🤣🤣❤️

By your grammar, I would say "lucky guess".

Thank you for explaining that it's actually a Coulomb explosion rather than a hydrogen explosion like most people think. If anyone needs Sodium metal, I sell it and have tons. I also have several videos on my channel showing everything below Rubidium in the alkali metals group exploding in water. We even blow up fish tanks with Sodium on a regular basis. Lmao! One thing he doesn't mention is that the majority of costs on Sodium orders goes towards packaging and shipping due to it having to be shipped a special way due to its dangerous reactivity. Any seller who ships it without at least 2-3 layers of protective layers of containment such as sealed bags and a lot of bubble wrap and a strong container that sits dead in the middle of the packaging. It must contain any and all leaks and render any spills harmless. Most sellers don't do most of this and refuse to ship properly, endangering customers and shipping service employees. I can guarantee you that no eBay seller besides me ships it correctly. Not going to write out names, but we all know who they are. That's the only reason they can be cheaper than me as we operate on paper thin margins after donating our profits and a LOT of chemicals and elements to help struggling science and chemistry based KZread channels make better and better videos.

I had a nice sealed glass ampule with a few grams of mercury that broke. So now I have it in a flask with a stopper. If you are able to reseal it in a glass ampule like he had his cesium in, I’d love to talk. Much safer I feel for display purposes than a flask where someone could just pull the stopper.

In Australia a small capsule of Cesium 137 was lost in transport, it made headlines for days as they searched hundreds of kms or road on foot to find it. Crazy how the same element can be so dangerously radioactive

I'm from Goiania, Brazil, where the biggest incident with Cesium 137 happend. People found a glowing blue rock and started walking around with it, turning their food blue and so on...

Hey yep well this guys live expectancy isn’t going to be great!. Cesium emits large amounts of gamma and beta radiation. Gamma obviously is hard to contain hence the thick concrete walls in nuclear facilities, I know their dealing with larger amounts. But still holding a vile of cesium is idiotic as that glass won’t prevent the gamma rays to be absorbed into his body!. If he says it is enough to block it he’s a prat!. Like you said look at the lengths Australia took over a tiny amount of cesium yet this guys playing with it!. Don’t tell me he this video is thinking oh wait brooo this is just cesium metal it’s fine…cesium is radioactive all cesium is radioactive 🤦‍♂️. He’s on the short lis for a Darwin Award.

​@@dejavukingyou are the one who will probably end in the darwin awards for your dumbness, the radioactive one is an isotope, they are not the same OF COURSE, you don't need to be a chemistry genious to see this
