... This leads to a reduction of the REE3+ ionic radius with increasing Z, a phenomenon which is known as Lanthanide contraction. Figure 1 shows the ionic radii (VI) of the most common REE ions. The REEs have moderate electronegativity between 1.0 and 1.2 duly forming bond with an elevated ionic compone ...

History of geology
The history of geology is concerned with the development of the natural science of geology. Geology is the scientific study of the origin, history, and structure of the Earth. Throughout the ages geology provides essential theories and data that shape how society conceptualizes the Earth.
