镧系锕系元素的重新界定与32列元素周期表

Redefinition of Lanthanides and Actinides——32 lines periodic table

阐述了重新界定镧系、锕系元素的理由,提出了f区元素与d区元素的新概念。对现有元素周期表的排列提出了新的建议。编制了32列元素周期表,提出了增加C族的想法。

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.
