Interactive Periodic Table of Mendeleev shows how we use all these elements

Periodic system of chemical elements (Mendeleev's table) is the classification of chemical elements, which establishes the dependence of various properties of elements on the charge of the atomic nucleus. The system is a graphic expression of the periodic law established by the Russian chemist DI Mendeleev in 1869. Its initial version was developed by DI Mendeleev in 1869-1871 and established the dependence of the properties of the elements on their atomic weight (in modern terms, on the atomic mass). In total, several hundred variants of the image of the periodic system (analytical curves, tables, geometric figures, etc.) have been proposed. In the modern version of the system, it is supposed to reduce the elements to a two-dimensional table, in which each column (group) determines the basic physicochemical properties, and the lines represent periods that are similar to each other to a certain extent.

We all know the common elements of our Planet, for example, everyone knows oxygen and helium, since they are used in everyday life. But gallium? Selenium? Rhodium? Keith Enevoldsen has created an interactive periodic table that shows exactly where you can encounter in your life with such unique and even obscure elements in the figure. It's like learning a university course anew, except for tests, and the allowed cheat sheet on your phone.
