Mendeleev wrote about the elements in front of hydrogen: “The chosen subject long occupied my thoughts, but for various reasons I didn’t want to talk about it, especially because those few clarifications that I thought could withstand criticism did not satisfy me, and I I expected everything from the experiments with which I intended to continue my first attempts, answers that were more encouraging in the correctness of the born conclusions. However, the years went away, the more persistent ones were torn off, and no one touched a question that seemed burning to me, so I decided to say in relation to him what and how I can do, without pretending at all about his decision. ” Elements before hydrogen inevitably fall into the zero group. “This position of argon analogs in the zero group is a strictly logical consequence of understanding the periodic law,” stated D.I. Mendeleev. He allowed the existence of elements - X ("newtonium") and Y ("coronium") before hydrogen in the zero group. It should be recalled that Mendeleev had not been mistaken in his predictions of new elements! “When I applied a periodic law to analogues of boron, aluminum and silicon, I was 33 years younger, I had complete confidence that sooner or later the foreseeable must certainly be justified, because everything was clearly visible to me there. Justification came sooner than I could have hoped. Then I did not risk, now I risk. It needs determination. She came when I saw radioactive phenomena ... and when I realized that it was already impossible for me to postpone and that, perhaps, my imperfect thoughts would lead someone on a path more faithful than the possible one that seems to my weakening sight. " D.I. Mendeleev did not have time to solve this problem, and his students and followers tried to forget this topic as “erroneous”. It should be noted that after D.I. Mendeleev's question about “zero” elements was repeatedly raised by many authors both in the past and in the present centuries, however, for brevity, we only mention the very first and most famous ones: for example, Ernest Rutherford in 1920 and Andreas von Antropoff in 1926 as the designation for a hypothetical element with atomic number zero, which it placed at the beginning of the periodic table. A. Antropoff was the first to suggest the term "neutronium". Currently, neutron matter, like neutron stars, is a recognized reality in astro- and nuclear physics. Neutron matter from the standpoint of General chemistry can be classified as chemically simple (that is, it cannot be decomposed into simpler chemical means), then inevitably the question arises about the Element corresponding to it, and its place in the Periodic System. Based on the logic of the Periodic Law - (ordinal number - electric charge) - the ordinal number of neutron matter will correspond to zero, which makes us remember and develop the ideas of Dmitry Ivanovich Mendeleev about the zero group and period. p.49
