Bassett's Vertical Arrangement

Bassett's Vertical Arrangement is actually designed to be a three dimensional formulation. Quam & Quam's review paper states:

"This table resembles Mendeléeff's vertical arrangement. The Cs period, however, starts far above the horizontal line of K and Rb, thereby giving space to the known and predicted elements of that period. The alkali metals appear in three horizontal lines. Co and Ni are arranged in order of their atomic weights.

"Bassett suggested cutting out the table and rolling it onto a cylinder of such circumference that similar elements would fall in line in Groups. For instance, Li, Na, K, Rb, and Cs would then fall on a line parallel to the axis of the cylinder."
