  • Description
  • Programme

The concept of atom, as well as that of element, comes from the Greeks: Empedocles, Democritus and Aristotle, in particular, dealt with the subject and, since ancient times, something like half a dozen of them had been known. As more and more elements were discovered and, likewise, their ability to combine to give diverse chemical species, Chemistry, freed from Alchemy, was generating a body of doctrine that culminates in Dalton, Lavoisier and many other scientists who considered experimentation as their first support.

The idea of ​​the periodicity of the chemical properties of the elements also has several promoters, among which Meyer in particular stands out and, above all, Mendeleyev who, 150 years ago, established a Periodic Table that classified the chemical elements into columns and rows. That is in Groups and Periods of elements based on their atomic weight that, intuitively, reflects the periodicity of all chemical properties of elements and compounds.

After the discovery of the electron (Thomson, 1897) and of the atomic nucleus (Rutherford, 1911) and the development of spectroscopy, in particular of X-rays (Moseley 1913), it was possible to establish that, it is precisely the way in which electrons are arranged in the atoms, the electronic configuration, that is responsible for the periodicity and, in fact, of the chemical behavior of the 118 different atoms that make up the Universe.

The International Year of the Periodic Table, officially declared by the UN, highlights both the tremendous intuition of the scientists who proposed it and the importance it has to explain and even predict the behavior of Matter in Nature.
