LANTHANOID Meaning and
Definition
-
Lanthanoid is a term used to describe any of the series of fifteen chemical elements known as the lanthanides. These elements are found in the periodic table in group 3, which is located between the alkaline earth metals and the transition elements. Lanthanoids include the elements from atomic number 57 (lanthanum) to atomic number 71 (lutetium), and they are characterized by similar chemical properties.
Lanthanoids are often referred to as rare earth elements due to their limited abundance in the Earth's crust. They have a silvery-white metallic appearance and are quite soft and malleable. One of the most notable characteristics of lanthanoids is their ability to exhibit a range of oxidation states, making them very reactive and useful in various applications. They are commonly used in the production of permanent magnets, catalysts, optical lenses, and lighting devices.
Due to their similar chemical properties, lanthanoids are often grouped together and studied as a unit. However, each element within the series has unique properties and applications. Despite their name, lanthanoids are not lanthanum-based; lanthanum simply acts as the first element of the series.
In summary, lanthanoids are a series of fifteen chemical elements known as the lanthanides, found in group 3 of the periodic table. They possess similar chemical properties, exhibit a range of oxidation states, and are widely used in various industrial applications.

Etymology of LANTHANOID
The word "lanthanoid" is derived from the root word "lanthanum", which is one of the elements in the lanthanide series. Lanthanum was discovered by Swedish chemist Carl Gustaf Mosander in 1839 and named after the Greek word "lanthanein", meaning "to escape notice", due to its initially obscure and often overlooked nature. The term "lanthanoid" was later coined to describe the entire group of elements with similar properties to lanthanum, and it is derived from the name of its parent element.
