The oldest surviving periodic table has been found by chance
Scottish scientists admit it’s amazing what things can be discovered by cleaning out warehouses. They are curious about what other secrets the old stashes hide. The table was found by Alan Aitken of the University of St Andrews. He was the one who took care of cleaning up the warehouse located under the lecture halloIn chemistry and there came across a unique monument.
Between the standard pieces of laboratory equipmentochemical also included numerous wall diagrams to help guide the lectureow. Amongod them Aitken discovered the oldest known copy of the periodic table.
It was produced in Germany. Scientists from the University of California analyzed the elements on it and concluded that it must have been created between 1879 and 1886. The element named germanium, discovered in 1886, is not on the system. Instead, there are gallium and scandium, whichore discovered in 1875 and 1879.
At the same time, a study of old documentoat the university’s. In financial books, it was discovered that the periodic table zamow were published in 1885 by a publisher based in Vienna.
The periodic table of the elementsow was created by Russian chemist Dmitri Ivanovich Mendeleev in 1869. This year marks the 150th anniversary of its creation. On this occasion, 2019 has been recognized by the United Nations as the Year of the Periodic Table of Elementsow.
But despite its age, the system is still growing. In 2016, four new elements were added to it (for more on this, see: Four new elements given names). Recently added elements having more than 104 protons and are called "superheavy". They are still quite a mystery to science, because, created in the laboratory, they exist for only fractions of a second, after which they disintegrate, in other words, they are very unstable.
It has been confirmed that the find is now the oldest surviving copy of the periodic table of the elementsoin the world. It was produced less than 20 years after Mendeleev announced the discovery. The board has undergone maintenance and repair. Will now be on display at the University of St Andrews. Its faithful copy wroShe also ciated the chemistry department, where the discovery was made.
