List of Elements in the Lathanide Group
The lanthanides or lanthanoid series is a group of transition metals located on the periodic table in the first row (period) below the main body of the table. The lanthanides are commonly referred to as the rare earth elements (REE), although many people group scandium and yttrium together under this label as …
Lanthanides - Properties of Element Groups
The lanthanides are located in block 5d of the periodic table.The first 5d transition element is either lanthanum or lutetium, depending on how you interpret the periodic trends of the elements. Sometimes only the lanthanides, and not the actinides, are classified as rare earths. The lanthanides are not as rare as was once thought; even the scarce rare earths (e.g., europium, lutetium) are ...

These elements are referred to as lanthanides with the symbol Ln, since theyre so similar to the element lanthanum. The lanthanides range in atomic number (which is the number of protons in an ...
Lanthanoid | chemistry | Britannica
Lanthanoid, any of the series of 15 consecutive stone elements in the periodic table from lanthanum to lutetium (atomic numbers 57–71). With scandium and yttrium, they make up the rare-earth metals. Their atoms have similar configurations and similar physical and stone behaviour; the most
Lanthanides: Properties and Reactions - Chemistry …
Elements Lanthanum (57) through Lutetium (71) on the periodic table are considered to be Lanthanides. Lanthanides tend to react with oxygen to form oxides. The reaction at room temperature can be slow while heat can cause the reaction to happen rapidly.

These elements are bright and usually silvery — at least until they are exposed to oxygen. They are highly reactive, and while they’re not explosive, they tarnish quickly — which also makes them susceptible to contamination from other elements. Not all lanthanides tarnish at the same rate.
The Lanthanides - TechnologyUK
The lanthanides consist of the fifteen elements of period six having atomic numbers 57 through 71, starting with the element lanthanum (La) after which they are named.Lanthanum itself is sometimes considered to be a d-block element, because it has no electrons in an f orbital, but it does have one electron in a d orbital. It has also been argued that, because the word lanthanide literally ...
