Samarium is a silvery metal in the lanthanoid group. It is one of the rare earth elements.[1]
It is named after the mineral samarskite which, in turn, was named after Vasili Samarsky-Bykhovets, the Chief of Staff (Colonel) of the Russian Corps of Mining Engineers from 1845–1861, thus making samarium the first chemical element to be named after a living person.
