The Place of Argon Among the Elements

Nature volume 52, page 278 | Download Citation



THE position of argon in a classification of the elements depending on atomic weights has been recently defined by C. J. Reed (Journal of the Franklin Institute, July). The elements are assigned positions on a plane determined by abseissæ proportional to their atomic weights and ordinates proportional to their valency. Oxygen is assumed to have an electronegative valency 2, and the valency of other elements is referred to this as standard; electro-positive valency is measured upwards, electro-negative downwards from the zero-axis. Under these conditions most of the elements fall on a peculiar series of double, equi-distant, parallel straight lines, connecting elements in order of their atomic weights and separated alternately by distances corresponding to one and sixteen units of atomic weight respectively.
