The Element Dysprosium

What is Dysprosium? Element Properties & Periodic Table Info


Definition of the Dysprosium Element
A soft, silvery rare-earth element used in nuclear research. It reacts with cold water and rapidly dissolves in acids. The Atomic Number of this element is 66 and the Element Symbol is Dy.

 

Origin / Meaning of the name Dysprosium
The name originates from the Greek word 'dysprositos' meaning 'hard to get at' due to the difficulty in separating this rare earth element from a holmium mineral in which it was found..

 

Periodic Table Group and Classification of the of the Dysprosium Element
Elements can be classified based on their physical states (States of Matter) e.g. gas, solid or liquid. This element is a solid. Dysprosium classified as an element in the Lanthanide series as one of the "Rare Earth Elements" which can located in Group 3 elements of the Periodic Table and in the 6th and 7th periods. The Rare Earth Elements are divided into the Lanthanide and Actinide series. The elements in the Lanthanide series closely resemble lanthanum, and one another, in their chemical and physical properties. Their compounds are used as catalysts in the production of petroleum and synthetic products. Nearly 75% of all the elements in the Periodic Table are classified as metals which are detailed in the List of Metals.

Facts about the Discovery and History of the Dysprosium Element
Dysprosium was discovered by Paul Emile Lecoq de Boisbaudran  in France in 1886.

What is Dysprosium - IUPAC and the Modern Standardised Periodic Table
The Standardised Periodic Table in use today was agreed by the International Union of Pure Applied Chemistry, IUPAC, in 1985 and now recognises more periods and elements than Dimitri  Mendeleev knew in his day in his day but still all fitting into his concept of  the "Periodic Table" in which Dysprosium is just one element that can be found.
