Rare Earth Metals included on the Periodic Table based on the IOUPAC 1985 standard

What are Rare Earth Metals? Define Rare Earth Metals
Rare Earth Metals are used as a term in Periodic Chemistry when classifying the chemical elements. Each element can usually be classified as a metal or a non-metal based on their general Chemical and Physical Properties. The rare earths share many common properties. This makes them difficult to separate or even distinguish from each other. Rare Earth Metals are any of the metallic elements within Group 3 in the Periodic Table (see the List of Rare Earth metals). Rare Earth metals are a set of 17 chemical elements in the periodic table, specifically the fifteen lanthanoids plus scandium and yttrium. All lanthanoids are relatively soft and reactive metals.

 

What are Rare Earth Metals? Common Properties of Rare Earth Metals
The rare earths metals are silver, silvery-white or gray metals which have a high luster, but tarnish readily in air. The rare earth metals have high electrical conductivity. Nearly 75% of all the elements in the Periodic Table are classified as metals which are detailed in the
List of Metals.

Common properties of Rare Earth metals
The elements classed as "Rare Earth metals" have the following properties in common:

  • Silver, silvery-white, or gray metals
  • High Luster
  • Tarnish in air
  • Have a high electrical conductivity

Rare Earth - Chemical Elements in the Periodic Table
The elements contained in the classification of Rare Earth are as follows:
 

Elements classified as Rare Earth
The elements classified as "Rare Earth Elements" are located in Group 3 of the Periodic Table and in the 6th and 7th periods. The Rare Earth Elements are of the Lanthanide and Actinide series. Most of the elements in the Actinide series are synthetic or man-made.

 

Elements in the Periodic Table are classified as follows:
  • Metalloids
  • Alkali Metals
  • Alkaline Earth Metals
  • Transition Metals
  • Other Metals
  • Non-metals
  • Halogens
  • Noble Gases
  • Rare Earth Elements

Compare the properties of the elements classified as Rare Earth with the other group classifications via Periodic Table Groups and using the Periodic Table.
