Samarium is a chemical element; it has symbol Sm and atomic number 62. It is a moderately hard silvery metal that slowly oxidizes in air. Being a typical member of the lanthanide series, samarium usually has the oxidation state +3.

Samarium is a silvery white, bright and hard metal. It is one of the lanthanide and is a rare earth metal. Its hardness and density are like zinc. Samarium is paramagnetic (material is weakly attracted by external magnets). Upon cooling on 14.8K the metal transform to antiferromagnetic state (magnetic movement related to the spin of electrons).

Samarium is a rare earth element that - indirectly - has the distinction of being the first naturally occurring chemical element to be named after a living person. Samarium was isolated from the mineral Samarskite which was discovered near the small town of Miass in the southern Ural mountains in 1847.

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. It rapidly dissolves in diluted …

Samarium is one of the rare earth elements used to make carbon arc lights which are used in the motion picture industry for studio lighting and projector lights. Samarium also makes up about 1% of Misch metal, a material that is used to make flints for lighters.

Samarium (pronunciation seh-MER-ee-em [2]), represented by the chemical symbol Sm [1], is a bright, fairly hard lanthanide element belonging to the family of rare earth metals [1, 3]. It has seven known natural isotopes with mass numbers 144, 147, 148, 149, 150, 152 and 154.

Samarium atom is a lanthanoid atom and a f-block element atom. ChEBI Samarium has been used in trials studying the treatment and prevention of Pain, Cancer, Metastasis, Prostate Cancer, and Metastatic Osteosarcoma, among others.

2024年1月28日 · Samarium is a chemical element with the symbol Sm and atomic number 62. This metal is a member of the lanthanide series on the periodic table. Although the “ rare earths ” is another name for the lanthanides series, samarium is not actually that rare. Samarium was discovered in 1879 by the French chemist Paul Émile Lecoq de Boisbaudran.

2023年7月9日 · Samarium is a chemical element with an atomic number 62 and is represented by the symbol ‘Sm’ in the periodic table. It is soft and silvery-white in appearance classified as rare earth metal and belongs to the f-block of the lanthanide group of the periodic table. Samarium generally has an oxidation state of +3.

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.
