Mendelevium (also known as unnilunium, Unu) is a synthetic element in the periodic table with the symbol Md (formerly Mv) and the atomic number 101. A metallic radioactive transuranic element of the actinides, mendelevium is synthesized by bombarding einsteinium with alpha particles and was named after Dmitri Mendeleev.
Notable characteristics
Researchers have shown that mendelevium has a moderately stable dipositive (II) oxidation state in addition to the more characteristic (for actinide elements) tripositive (III) oxidation state. 256Md has been used to find out some of the chemical properties of this element while in an aqueous solution. There are no other uses of mendelevium and only trace amounts of the element have ever been produced.
History
Mendelevium (for Dmitri Mendeleyev, surname commonly spelt as Mendeleev, Mendeléef, or even Mendelejeff, and first name sometimes spelt as Dmitry or Dmitriy) was first synthesized by Albert Ghiorso (team leader), Glenn T. Seaborg, Bernard Harvey,Greg Choppin, and Stanley G. Thompson in early 1955. The team produced 256Md (half-life of 76 minutes) when they bombarded an 253Es target with alpha particles (helium nuclei) in the Berkeley Radiation Laboratory's 60-inch cyclotron (256Md was synthesized one-atom-at-a-time). Element 101 was the ninth transuranic element synthesized. More on [ Mendelevium ]
When I was 12 we learned about mendelevium on the periodic table and I told everyone I was in love with Dmitri Mendeleev. #iwasntjoking

yes its a common practice. google mendelevium RT @reeciecups: @taut_7 name it after you? is that common practice? how vain. lol
