Who created samarium?
Paul-Émile Lecoq de Boisbaudran
Samarium was first isolated by Paul-Émile Lecoq de Boisbaudran in Paris in 1879. While analysing didymium’s atomic spectrum, Boisbaudran suspected it was composed of more than one element. So he extracted didymium from samarskite, made a solution of didymium nitrate and added ammonium hydroxide.
What is an interesting fact about samarium?
Samarium is a yellowish silver-colored metal. It is the hardest and the most brittle of the rare earth elements. It tarnishes in air and will ignite in air at about 150 °C. Under ordinary conditions, the metal has rhombohedral crystals.
What family does samarium belong?
lanthanide group
Samarium is a silvery-white metal belonging to the lanthanide group of the periodic table.
What color is samarium?
silvery white
samarium (Sm), chemical element, a rare-earth metal of the lanthanide series of the periodic table. Samarium is a moderately soft metal, silvery white in colour.
What is the atomic number of samarium?
62
Samarium/Atomic number
How much is samarium worth?
Samarium costs about $5 per gram, around a third of the price of gold. Samarium’s primary use is in samarium cobalt alloy magnets, which are particularly powerful; these are used in consumer applications such as headphones as well as in industrial contexts.
Is samarium a rare earth metal?
samarium (Sm), chemical element, a rare-earth metal of the lanthanide series of the periodic table. Samarium is a moderately soft metal, silvery white in colour.
What is samarium on the periodic table?
samarium (Sm), chemical element, a rare-earth metal of the lanthanide series of the periodic table. Samarium is a moderately soft metal, silvery white in colour. It is relatively stable in air, slowly oxidizing to Sm2O3.
How did samarium get its symbol?
Samarium is a chemical element with the symbol Sm and atomic number 62….

What type of element is Samarium?
samarium (Sm), chemical element, a rare-earth metal of the lanthanide series of the periodic table. Samarium is a moderately soft metal, silvery white in colour.
When was samarium first observed?
Samarium was observed spectroscopically by Jean Charles Galissard de Marignac, a Swiss chemist, in a material known as dydimia in 1853. Paul-Émile Lecoq de Boisbaudran, a French chemist, was the first to isolate samarium from the mineral samarskite ( (Y, Ce, U, Fe) 3 (Nb, Ta, Ti) 5 O 16) in 1879.
How do you make samarium?
The Element Samarium. Today, samarium is primarily obtained through an ion exchange process from monazite sand ( (Ce, La, Th, Nd, Y)PO 4 ), a material rich in rare earth elements that can contain as much as 2.8% samarium.
What is the oxidation state of samarium?
In clay soil, there may be over a thousand times more samarium at the surface than further down. The most common oxidation state of samarium is +3 (trivalent). Most samarium salts are pale yellow in color. An approximate cost of pure samarium is about $360 per 100 grams of metal.
