It is most often recovered commercially from monazite sand (0.03% ytterbium). The element is also found in euxenite and xenotime. The main mining areas are China, the United States, Brazil, India, Sri Lanka, and Australia. Reserves of ytterbium are estimated as one million tonnes.
What is holmium most commonly used for?
Uses of Holmium As a result of its special magnetic properties, holmium is used in alloys for the production of magnets and as a flux concentrator for high magnetic fields. Holmia (holmium oxide) is used as a yellow or red coloring for glass and cubic zirconia.
How is rutherfordium used in society?
Because rutherfordium is made within the lab, there are not very many uses for this element commercially. On the other hand, rutherfordium has been used within the laboratory setting to conduct research. Most elements that are highly radioactive are used for nuclear power and medicinal purposes.
What compounds is holmium found in?
Holmium forms no commercially important compounds. Some of holmium’s compounds include: holmium oxide (Ho2O3), holmium fluoride (HoF3) and holmium iodide (HoI3).How is holmium mined?
Pure holmium can be obtained through the reduction of holmium fluoride with calcium metal. Commercially, it is extracted mainly from monazite or gadolinite ores with sodium hydroxide, hydrochloric acid or sulfuric acid through ion exchange chromatography or solvent extraction techniques.

How common is ytterbium?
Ytterbium is the 44th most abundant element in the Earth’s crust. It is one of the more common rare earths, present at about 2.7 to 8 parts per million in the crust. It is common in the mineral monazite.
What is ytterbium used for in the world?
Ytterbium has few uses. It can be alloyed with stainless steel to improve some of its mechanical properties and used as a doping agent in fiber optic cable where it can be used as an amplifier. One of ytterbium’s isotopes is being considered as a radiation source for portable X-ray machines.
What is lawrencium used for in everyday life?
Lawrencium has no uses outside research. Lawrencium has no known biological role. Lawrencium does not occur naturally. It is produced by bombarding californium with boron.
Where is vanadium used?
Vanadium can be used to make steel alloys, for use in space vehicles, nuclear reactors and aircraft carriers, etc. Vanadium steel alloys’ strength means that they are perfectly suited to the creation of tools, axels, piston rods and as girders in construction. Vanadium can be utilised in ceramics as a pigment.
Who made the first periodic table?
In 1869, Russian chemist Dmitri Mendeleev created the framework that became the modern periodic table, leaving gaps for elements that were yet to be discovered.
How is rutherfordium produced in a lab?
Source: Rutherfordium is a synthetic radioactive metal, created by nuclear bombardment, and has only been produced in tiny amounts. Rutherfordium can be made by bombarding plutonium-242 with accelerated neon ions or by bombarding californium-249 with accelerated carbon ions.
What are three interesting facts about rutherfordium?
Rutherfordium has 12 recognized isotopes with known half-lives. The most stable is 263Rf, which has a half-live of ten minutes. It decays through spontaneous fission. Rutherfordium is produced artificially and only small amounts have been made.
When and where was holmium found?
Holmium was discovered at Geneva in 1878 by Marc Delafontaine and Louis Soret, and independently by Per Teodor Cleve at Uppsala, Sweden.

What type of metal is holmium?
holmium (Ho), chemical element, a rare-earth metal of the lanthanide series of the periodic table. Holmium is a moderately hard, silvery white metal that is relatively stable in air.
Where is thulium found?
The element is never found in nature in pure form but it is found in small quantities in minerals with other rare earths. It is principally extracted from monazite, which contains about 0.007% of thulium and bastnasite (about 0.0008%). The chief ores are in China, US, Brazil, India, Sri lanka and Australia.
Where is erbium found?
Erbium is never found as a free element in nature. It is found in minerals that include all the rare-earth elements. Erbium is one of the more abundant rare-earth elements. The main mining areas are China and US.
Who discovered holmium?

What element family is rutherfordium?
In the periodic table of the elements, it is a d-block element and the second of the fourth-row transition elements. It is a member of the 7th period and belongs to the group 4 elements. Chemistry experiments have confirmed that rutherfordium behaves as the heavier homologue to hafnium in group 4.
Why is rutherfordium an element?
On the periodic table of elements, rutherfordium is represented by the symbol Rf. It has an atomic number of 104 because it has 104 protons in its nucleus. It is a synthetic element because it is created in a laboratory rather than occurring naturally.
