What elements does samarium bond with?
Samarium metal reacts with all the halogens to form samarium(III) halides. So, it reacts with fluorine, F2, chlorine, Cl2, bromine, I2, and iodine, I2, to form respectively samarium(III) bromide, SmF3, samarium(III) chloride, SmCl3, samarium(III) bromide, SmBr3, and samarium(III) iodide, SmI3.
How many shells does samarium have?

Where is samarium on the periodic table?
Samarium is a chemical element with symbol Sm and atomic number 62. Classified as a lanthanide, Samarium is a solid at room temperature.
What type of element is samarium?
earth metal
Samarium is a rare earth metal with a pronounced silver lustre. It oxidizes in air and ignites spontaneously at 150 degrees centigrade. Rare Earth metals are a collection of seventeen chemical elements which include scandium, yttrium and fifteen lanthanoids.
What is samarium chemical properties?
Samarium is a silvery-white metal belonging to the lanthanide group of the periodic table. It is relatively stable at room temperature in dry air, but it ignites when heated above 150 C and forms an oxide coating in moist air. Like europium samarium has a relatively stable oxidation state (II).
How is samarium extracted?
The metal is often prepared by electrolysis of a molten mixture of samarium(III) chloride with sodium chloride or calcium chloride. Samarium can also be obtained by reducing its oxide with lanthanum. The product is then distilled to separate samarium (boiling point 1794 °C) and lanthanum (b.p. 3464 °C).
What is samarium found in?
1879
Samarium/Discovered
Samarium was isolated as an impure oxide and spectroscopically identified as a new element in 1879 by French chemist Paul-Émile Lecoq de Boisbaudran. Samarium occurs in many other rare-earth minerals but is almost exclusively obtained from bastnasite; it is also found in products of nuclear fission.
