Japanese scientists from Kyoto University have developed a new periodic table of elements. Unlike the famous periodic table, it is based not on the similarity of the chemical properties of elements, but on the behavior of protons in the nucleus.
The starting point for scientists was a list of nuclei with fully filled proton shells. These are helium, oxygen, calcium, nickel, tin, lead and an element of flerovium. These elements react with others only in special cases.
“Our nuclear periodic table also shows that the nuclei, as a rule, have a spherical shape near magic numbers, but deform when they move away from them,” says one of the authors of the table, Kouichi Hagino.
