What is holmium used for?
Holmium can absorb neutrons, so it is used in nuclear reactors to keep a chain reaction under control. A magnetic pole piece with magnetic iron powder to demonstrate that Holmium has the highest magnetic strength of any element. Holmium is used in alloys for the production of magnets.
How do you identify dysprosium?
dysprosium (Dy), chemical element, a rare-earth metal of the lanthanide series of the periodic table. Dysprosium is a relatively hard metal and is silvery white in its pure form. It is quite stable in air, remaining shiny at room temperature. Dysprosium turnings ignite easily and burn white-hot.
How do you make dysprosium?
4 Dy + 3 O2 → 2 Dy2O. Dysprosium is quite electropositive and reacts slowly with cold water (and quite quickly with hot water) to form dysprosium hydroxide: 2 Dy (s) + 6 H2O (l) → 2 Dy(OH)3 (aq) + 3 H2 (g)
What atom of an element contains 66 electrons?
Dysprosium is the chemical element with the symbol Dy and atomic number 66.
Where is dysprosium found in the world?
Dysprosium is chiefly obtained from bastnasite and monazite, where it occurs as an impurity. Other dysprosium-bearing minerals include euxenite, fergusonite, gadolinite and polycrase. It is mined in the USA, China Russia, Australia, and India.
How is dysprosium used in everyday life?
Dysprosium is used in data storage applications such as compact discs and hard discs. It is also used in medium source rare-earth lamps (MSRs) in the film industry. Dysprosium iodide is used these lamps to produce an intense white light. With vanadium, dysprosium is used in laser materials.

What is er in periodic table?
erbium (Er), chemical element, a rare-earth metal of the lanthanide series of the periodic table.
What does dysprosium look like?
Characteristics: Dysprosium is a bright, soft, silvery-white, rare earth metal. It tarnishes slowly in air at room temperature and dissolves in both dilute and concentrated acids. Dysprosium and holmium have the highest magnetic strengths of any elements.
Why is there a periodic table of elements in PubChem?
Note that the periodic table of elements page is provided in order to help navigate abundant chemical element data available in PubChem – each element also has a dedicated page with a lot more information available about each element including references.
Who created the periodic table of elements?
The creator of the periodic table, Dmitri Mendeleev, in 1869 began collecting and sorting known properties of elements, like he was playing a game, while traveling by train.
