Alternative table were presented by scientists from Kyoto University.

Scientists from Kyoto University introduced the periodic table of the elements, which is in contrast to the periodic table, where the basis is taken from the electrons in the atom, based on the behavior of protons in the nucleus. Description a new table named authors Nucletouch in the journal FoundationsofChemistry, reports ria.ru.

For the theory of the shell structure of the nucleus in 1963 was awarded the Nobel prize in physics. According to this theory, structure of atomic nuclei presented in the form of nucleon shells filled with protons and neutrons, by analogy with the theory of atomic structure, the shell are filled with electrons.

“Periodic table of the elements Mendeleev is one of the most significant achievements in science, and in its familiar form it is based on the shell structure of electronic orbitals in atoms — are in the press release of Kyoto University the words of one of the authors of the new table Yoshiteru of Maeno (Maeno Yoshiteru). But atoms are composed of two types of charged particles, which determine each element electrons rotating around the nucleus, and protons in the nucleus”.

More than 150 years ago Dmitri Mendeleev discovered the periodic law, which was designed in the classic periodic table of elements. A brilliant scientist even left room for elements that were unknown in his time.

“In fact, in this system all boils down to the electrons in each atom. Atoms are considered stable when the electrons completely fill its shell orbit around the nucleus, continues Mr. Maeno. The so — called noble gases — inert elements such as helium, neon and argon, rarely react with other elements. Their most stable electronic numbers are 2, 10, 18, 36 and so on. This so-called magic numbers”.

The authors decided that the same principle can be applied to the protons, which have their “magic numbers” are 2, 8, 20, 28 and so on. They put items with these stable numbers of protons, helium, oxygen and calcium in the center of your table.

“Like electrons noble gases, nuclear orbit, filled with protons, ensure the stability of the nucleus, says second author of the discovery Koichi Hagino (Kouichi Hagino). In our nuclear periodic table we also see that the kernel tend to have spherical elements that are close to magic numbers, and deform away from them.”

The researchers hope that their proposed alternative way of presenting chemical elements will enable other scientists to take a new look at already known chemical and physical laws will lead to new discoveries.
