How did Jean Charles Galissard de marignac find ytterbium?

The first concentrate of ytterbium was obtained in 1878 by Swiss chemist Jean-Charles Galissard de Marignac and named by him for the town of Ytterby, Sweden, where it (and the first discovered rare-earth element, yttrium) was found….Read a brief summary of this topic.

What element has the atomic number of 73?

Tantalum
Tantalum now sits below niobium in the periodic table. It has an atomic number of 73, and an atomic weight of just under 181.

Is ytterbium toxic?

Once extracted and prepared, ytterbium is somewhat hazardous as an eye and skin irritant.

Is ytterbium harmful to humans?

Ytterbium and its compounds are not normally found in the human body. They are estimated to be of low to moderate toxicity. However, ytterbium is stored and treated as if it were a highly toxic chemical. Part of the reason is that metallic ytterbium dust presents a fire hazard, evolving toxic fumes as it burns.

What is 37 on the periodic table?

rubidium
So there we have rubidium, the explosive red element number 37 in the periodic table.

Where can ytterbium be found?

Ytterbium is found with other rare-earth elements in several rare minerals. 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.

Is ytterbium rare or common?

rare earths
The elements are now known as ytterbium and lutetium. Ytterbium is among the less-abundant rare earths. It occurs in minute amounts in many rare-earth minerals such as laterite clays, xenotime, and euxenite and is found in products of nuclear fission as well.

How is ytterbium found?

Ytterbium has no known biological role. It has low toxicity. In common with many lanthanide elements, ytterbium is found principally in the mineral monazite. It can be extracted by ion exchange and solvent extraction.

Is niobium a rare earth?

Niobium, a rare earth metal, is used in practically everything. Wind turbines, jet engines, airplane bodies, high-pressure pipelines, superconducting magnets, bridges, brake discs, and the steel frames of skyscrapers all become better, tougher, and more lightweight with a bit of niobium added.
