Have you connected your life with chemistry or just love chemistry? Be sure to visit our online store. We tried to collect all kinds of samples of chemical elements for you there. https://chemical-elements.ru We have traditional things, for example, cubes of different metals, chemical elements simply in jars, gases in ampoules, but we consider keychains with real chemical elements inside to be a unique thing, an idea that could not be realized for a long time due to the complexity of the technology, but now keychains are on the site. I hope we have created an interesting thing, and you will appreciate it. In this video, we will show you the spectroscopy of elements such as gallium, indium and thallium. And we will also tell the story of their discovery. Become a sponsor of the channel, and you will get access to exclusive bonuses.
