Dysprosium: The Rare Element Driving Modern Technology

Dysprosium: Everything You Need to Know About the Rare Earth MetalHave you ever heard of dysprosium? It’s a rare earth metal that you probably haven’t come across too often.

Dysprosium is one of the less commonly known elements in the periodic table, but it is used in various modern technologies, from electric cars to smartphones. In this article, we’ll explore everything you need to know about dysprosium, from its natural occurrence to its discovery and identification.

Dysprosium as a Rare Earth Metal

Dysprosium is a rare earth metal with the chemical symbol Dy and atomic number 66. It plays a vital role in modern technologies due to its unique magnetic and electrical properties.

Dysprosium is a silver-white metal, which oxidizes quickly in the air and is therefore commonly stored under a protective layer of oil or in sealed ampoules.

Natural Occurrence and Radioactive Isotopes

Dysprosium is a rare element with a natural abundance of 5.2 ppm (parts per million) in the earth’s crust. It mostly occurs in minerals such as xenotime, fergusonite, gadolinite, and euxenite, which are found in Australia, China, Brazil, and Canada.

Dysprosium also has 29 radioactive isotopes, with the most stable one being Dy-164.

Dysprosium Reserves and Producers

Currently, China is the world’s largest producer of dysprosium, followed by the United States, Australia, and Brazil. The reserves of dysprosium are limited, and the growing demand for this rare earth metal is putting pressure on the world’s supply.

This is why many countries are now exploring new methods to extract dysprosium from alternative sources, such as by recycling and urban mining.

Origin of Name and Discovery

Dysprosium’s name comes from the Greek word “dysprositos,” which means “hard to get at.” The name appropriately represents the difficulties scientists faced when attempting to isolate the element. Dysprosium was first discovered by French chemist Paul Emile Lecoq de Boisbaudran in 1886 while studying the mineral erbium.

Dysprosium Identification

The atomic number of dysprosium is 66, and its CAS (Chemical Abstracts Service) number is 7429-91-6. In the periodic table, it is found in the lanthanide series or rare earth elements, which are located in the seventh period of the table.

Dysprosium is a member of the yttrium group and has the electron configuration [Xe] 4f 6s.

Position in the Periodic Table

Dysprosium is a lanthanide element and is located in the f-block of the periodic table. Elements in the f-block have electrons filling the inner f orbitals, which results in them being placed in two rows at the bottom of the periodic table.

Like other lanthanides, dysprosium has similar chemical properties, and it is challenging to isolate and purify due to its closeness in properties to other rare earth elements. In conclusion, dysprosium is a rare earth metal with a silver-white appearance, commonly used in modern technologies such as electric cars and smartphones.

It is found in limited reserves globally, with China being the largest producer. Its discovery goes back to 1886, and the name signifies the difficulties associated with isolating the element.

Dysprosium’s unique magnetic and electrical properties make it an attractive element for modern technology.

General Properties

Physical Properties: Dysprosium is a silver-white metal that is relatively soft and malleable. It has a melting point of 1412 C and a boiling point of 2562 C.

Dysprosium is a relatively stable metal and does not react with air at room temperature. It is resistant to rust and corrosion, which makes it ideal for use in high-temperature applications.

Chemical Properties: Dysprosium is a highly reactive metal that readily forms compounds with other elements, such as oxygen, sulfur, and halogens. It has two common oxidation states: +3 and +2, with +3 being the most common.

Dysprosium is also paramagnetic, meaning that it is weakly attracted to magnetic fields. Isotopes: Dysprosium has 29 isotopes, with the most stable one being Dy-164.

Several other isotopes, such as Dy-154, Dy-160, and Dy-161, have been found to be radioactive.

Atomic Data

Valence Electrons and Quantum Numbers: Dysprosium has seven valence electrons and is part of the lanthanide series of elements. Its quantum numbers are n=6, l=3, m=0, and ms=+1/2.

Electron Configuration and Atomic Structure: Dysprosium has an electron configuration of [Xe]4f6s. The f-orbital contains seven electrons, with one electron occupying each of the seven orbitals.

The atomic structure of dysprosium is characterized by a large positive charge in the nucleus, which attracts the seven valence electrons. Radius and Electronegativity: The atomic radius of dysprosium is 2.57 , and its electronegativity is relatively low, at 1.22 on the Pauling Scale.
