The rare-earth elements (REE), also called the rare-earth metals or rare earths, and sometimes the lanthanides or lanthanoids (although scandium and yttrium, which do not belong to this series, are usually included as rare earths), [1] are a set of 17 nearly indistinguishable lustrous silvery-white soft heavy metals.
Lanthanide metals react exothermically with hydrogen to form LnH 2, dihydrides. [1] With the exception of Eu and Yb, which resemble the Ba and Ca hydrides (non-conducting, transparent salt-like compounds),they form black pyrophoric, conducting compounds [6] where the metal sub-lattice is face centred cubic and the H atoms occupy tetrahedral sites.

Dysprosium is a chemical element; it has symbol Dy and atomic number 66. It is a rare-earth element in the lanthanide series with a metallic silver luster. Dysprosium is never found in nature as a free element, though, like other lanthanides, it is found in various minerals, such as xenotime.
She added that "even seemingly innocuous items" such as plastic water bottles and storage containers can "contribute to our broader health picture." Patidar posted her video on Instagram in Oct. 2024.
Researchers have developed an inexpensive blood test that they say can detect pancreatic cancer — even in its early stages.. Using a small blood sample, researchers from Oregon Health & Science ...
On a human, it will be a little tricky.” Kato noted the following about continued research: “Research on age-related changes, including prevention of hair graying, is a long-term process.
Lanthanide chlorides are a group of chemical compounds that can form between a lanthanide element (from lanthanum to lutetium) and chlorine.The lanthanides in these compounds are usually in the +2 and +3 oxidation states, although compounds with lanthanides in lower oxidation states exist.
A Connecticut boy is among four children all born with severe childhood blindness who gained “life-changing improvements” to their vision after an experimental trial of gene therapy. Jace was ...
