At the time of creation, Mendeleev left spaces for elements that we had not yet discovered.ДЄlthough we credit the modern table display to this scientist, thereвЂ™s a difference in the display from that period. We recognize the Russian scientist Dmitri Mendeleev as the inventor of the periodic table framework as we know it today.

Apart from that, they also use it to understand chemical reactions and analyze reactivity.Д«efore we got to this stage of experiencing a periodic table with actual samples, the development had gone through many stages. Science geeks and scientists use the table to understand trends in the properties of real elements. Its function goes beyond helping people name and identifies the elements.

Science lovers and budding scientists will also proudly display the table in their homes as a statement piece reflecting their passion and interest. YouвЂ™ll find it on classroom walls, in between textbook pages, in libraries, and so on. The periodic table is an important tabular arrangement.

The product was marketed by PEARS AND PEACHES here on Instagram, it's incredible what type of crooks are out there - too bad when they sell to an analytical lab who can prove that they are doing illegitimate things. Pretty cool is also that the ignorant scammers marketing this product have found solid mercury

(see pictures) so basically the temperature within this table must be below 3 Kelvin (less than -270вЊ) and under pressure, the only condition under which helium exists as a solid!!! And besides, they put the two highly radioactive elements Uranium and Thorium, and surprise surprise, the laboratory grade Geiger counter does not pick up any radioactivity (plexiglass does not block radioactivity except for alpha particles.). The top of the top is that the idiot-scammers designing this knock-off have put 'elements' that exist only as gas at ambient conditions, helium, hydrogen, nitrogen, oxygen, fluorine, neon and argon, so basically they claim to have added solid forms of all these. So - lets see if I can get my hands on the real thing - somehow. Thanks to Friedrich Menges I just found out that this seems to be a knock-off sold by some fraudulent companies and not the one sold via the Kickstarter project I would indeed like to see the real thing though, as on the images I have seen there seems to be something in the 'gaseous elements' as well, which seems pretty absurd to me, and there is some material in the thorium and uranium field, which seems pretty dangerous to me. this is a real scandal, if indeed these pieces are from the Kickstarter project than everybody who helped financing this should be reimbursed immediately. and Pears and Peaches does not reply and does not reimburse the money paid. Kickstarter refused to investigate further, they don't see a problem. even more scandalous - this is supposed to be a Kickstarter financed product. Bought from PEARS AND PEACHES this table of elements that supposedly contains real elements embedded in the plexiglass block -> Д«biggest SCAM ever, there are no elements, only rudimentary pictures that are supposed to look like elements.
