Redefinition of Lanthanides and Actinides --32 lines periodic table |
| |
| Abstract: | The reason of redefining Lanthanides and Actinides is that the atomic structure of Sc,Y,Lu,Lr are more similar than that of Sc, Y, La, Ac. Therefore, Sc, Y, Lu, Lr should reasonably belong to the elements of ⅢB group. Once the position of Lu, Lr are fixed,there would be no specific position for Lanthanides and Actinides in new periodic table, they were pushed into a slit between s and d section.To solve this problem, we have worked out a new 32 lines periodic table. Boron(B) is the first element in the p section; Scandium(Sc) is the first element of d section; Lanthanum (La) is the first element of f section. It belongs to ⅢC group.We think that (La and Ac) belong to ⅢC, (Ce and Th) belong to ⅣC … (Pm and Np) belong to ⅦC, (Tm and Md) belong to ⅡC, (Yb and No)belong to ⅠC, ⅧC Group contains 14 elements they are Sm, Eu, Gd, Tb, Dy, Ho, Er, and Pu, Am, Cm, Bk, Cf, Es, Fm. |
