An Etymological Dictionary of Astronomy and Astrophysics
English-French-Persian

A graph displaying → atomic volumes of → chemical elements against their → atomic masses, first plotted by Lother Meyer (1830-1895). The elements with similar properties occupy the same positions on the graph. In the original curve, Lothar Meyer plotted atomic volumes against → atomic weights. → Alkali metals such as Na, K, Rb, and Cs occupy the top position on the graph. Elements like Be, Mg, Ca, Sr, and Ba occupy the positions on the ascending part of the graph. → Inert gases, except He, occupy the positions on the descending part of the graph. → Halogen elements like F, Cl, and Br also occupy the descending part of the graph.

→ atomic; → volume; → curve.
