抄録: The article entitled "Confusion in the Periodic Table of the Elements" appeared in "Jouranl of Chemical Education". This report is concerned only with the most general periodic table becomes very popular at present. However the result of the difference between two methods (Fig. 1 and Fig, 2) in the use of A and B in the periodic table is utter confusion. The ACS Committee on Nomenclature, at its meeting in November 1981, suggested some very important considera tions to keep in mind in investigating alternatives to the A and B system. Comments and suggestions from groups and individuals, especially from those active in education, are earnestly solicited. The author proposes to designate subgroups by the letters A, B and C, referring directly to electronic orbitals, sp, d and f. Also he proposes that Zn, Cd and Hg shoule be classified as transition elements and that the series of inner transition elements should be called ceriumides (58Ce~71Lu) in the place of lanthanides and thoriumides (90Th~103Lr) in the place of actmides.
