Abstract: In the paper "Confusion in the Periodic Table of the Elements" published in Journal of Chemical Education in the U. S., the American Chemical Society (ACS) has asked for an alternative suggestion to the traditional designations to avoid the present confusion caused by the use of some designations of A and B Groups III-VIII in a manner opposite to each in the subgroups of long, or expanded form of the Periodic Table. It is common knowledge that the same confusion prevails in Japan also. The author proposes to designate typical elements as Subgroup A, transition elements as Subghoup B and inner transition elements as Subgroup C. The private views that the elements Zn, Cd and Hg ought to be classified as the transition element and how to designate the inner transition element series will be stated hereafter.
