Caesium- Ion

 Cesium

 

Cesium is an active alkaline metal, which is located near the bottom of the periodic table of

chemical elements only Francium(Fr) can be more active than Cesium(Cs). but that metal is radioactive and a un insignificant amount of it was obtained in its pure form to do any experiments with it. because of its high activity, metallic Cesium is being stored in special ampules and inert atmosphere of either Argon or Hydrogen. Appearance-wise, Cesium has a yellowish tint like gold

. but the price for Cesium is still higher than Gold due to its extremely small sales market and its highest activity, the price of Cesium can reach over a¬100 per gram. The vial, 50 grams of cesium. Just imagine it's cost. Cesium is unusual, that it has a very low melting pointïng 29c. If you take a vial of Cesium in hand, you can see how quickly the metal begins to melt. Even while Cesium is still in the vial, we can already conduct an experiment with it. If you leave the liquid Cesium, in a vial for some time, it partially hardens, forming very beautiful crystals of pure Cesium Music Also, due to Cesium's solidification, its volume is being significantly reduced as can be clearly seen with a funnel formed from solidified Cesium in the ampule. Now, let's proceed to the most interesting part: conducting experiments with Cesium. Firstly, to get the Cesium out of the vial, I decided to melt it in the vial and then pour out the liquid Cesium in kerosene. However, something went wrong during that part. a cracking and screaming‘ The liquid Cesium instantly ignited in air, burning everything around it. That happened most likely due to the fact that the Cesium in the vial was liquid after the hammer happened, the top of the vial broke off, pouring Cesium onto the table is now out of use. For further experiments, we get to buy another vial of Cesium. Now I decided to do things differently: break the end of ampule with solid Cesium and then heat in kerosene This all turned out well, gradually the liquid Cesium began to flow from the vial into the kerosene.

After reach, it immediately lost its golden shine and get covered with a layer of oxides and peroxides. Due to the impurity of water and oxygen in kerosene, I have decided to destroy the vial with the remains of liquid Cesium by throwing it onto a wet wall. Explosion After solidifying, the Cesium can be easily cut, even with a spatula. And it is not just the most active, but also the softest metal in the world. It resembles margarine for its softness. Igniting Cesium on the sand, similarly to rubidium, Cesium reacts with the silica which the sand consists of very calmly and forms a beautiful sandy surface and also,  amorphous silicon. Next, I decided to let hot Cesium react with manganese sulfate, the response wasn't very rough. But it is better than it was with sand when it's formed metal manganese. The coolest reaction by far was Cesium with sulfur. Where we throw the piece of Cesium in molten sulfur. 【crack and explosion‘ In that reaction the two elements form Cesium sulfide. Also, we decided to fuse copper with cesium, with that an unusual compound was formed, the intermetallic compound of copper and cesium which eventually decayed due to cesium's oxidation by atmospheric oxygen. If you throw a piece of Cesium into the glass filled with ethanol, Cesium will self ignite even in alcohol, coloring the flame of alcohol to beautiful purple due to Cesium ions. Lastly, we decided to throw about 20 grams of Cesium in a container filled with ice water. Explosion As you can see, Cesium explodes on the first contact with water. Although not so strongly as it's sometimes portrayed in other videos. Cesium has a variety of applications, these days metallic Cesium is used in the most accurate atomic clocks. The error of which is only a second per 100 million years. Also, Cesium is used in the new engines for orbital satellites. Until about the early 2000s, before the rise of microelectronics, Cesium has been widely used in photocells and motion sensors. However, after the market has been flooded with cheap transistor analogies, the need for such a number of manufacturing metallic cesium disappeared and the price had since arisen sharply. Furthermore, in conclusion, and viewer, who would learn a lot about this amazing metal, Cesium.
