RARE EARTH ELEMENTS — YTTRIUM AND HIGHER PLANTS* ABSTRACT: Rare earth elements (REEs) form a chemically uniform group with very similar physical and chemical properties. The REEs include the elements scandium, yttrium, and the lanthanides from lanthanum to lutetium. They are widely distributed and...
Rare-earth element, any member of the group of chemical elements consisting of three elements in Group 3 (scandium [Sc], yttrium [Y], and lanthanum [La]) and the first extended row of elements below the main body of the periodic table (cerium [Ce] throug
(1802) by the Swedish chemistAnders Gustaf Ekebergand named after the mythological characterTantalusbecause of the tantalizing problem of dissolving theoxidein acids. Due to the great chemical similarity of niobium and tantalum, the establishment of the individual identities of the two elements was ...
Rare earth elements (REEs) refer to a group of 17 elements, including scandium (Sc), yttrium (Y), and the lanthanoid series (LaLu), located in group IIIB of the periodic table [1,2]. Owing to their unique spatial structure and physical and chemical properties, these elements find widesp...

Rare Earth Elements (REEs) refer to the 15 elements in the 4f series, ranging from La to Lu, in the periodic table. These elements typically carry a +3 ionic charge and exhibit a systematic decrease in their ionic radii as we move from La to Lu. ...
Rare Earth elements, largely unknown to the majority of the general public, have become national news in the past decade. The magnet industry has used samarium, neodymium, dysprosium and other rare earths for decades as they are a very important ingredient in magnet design. Many of these magnet...
The concentrations of rare earth elements (REEs) in plant leaves, soils in which they grow, and mother rocks were determined using Inductively Coupled Plasma-Atomic Emission Spectrometry (ICP-AES). Concentration levels of REEs in most plants were low. However, one of the herb species, pokeweed ...
