Mendelevium is an inner transition metal of the actinide series, situated in period seven of the periodic table, between fermium and nobelium.
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.
Mendelevium was named after Dmitri Mendeleev (surname also spelt as Mendeleyev, Mendelйef, or even Mendelejeff; first name sometimes spelt as Dmitry or Dmitriy).
Currently, there are no practical uses of mendelevium, and only trace amounts of the element have been produced.
A metallic radioactive transuranic element of the actinide series, mendelevium is synthesized by bombarding einsteinium with alpha particles.
Mendelevium (chemical symbol Md (formerly Mv), atomic number 101), also known as unnilunium (symbol Unu), is a synthetic element in the periodic table.
The isotopes of mendelevium range in atomic weight from 245.091 amu (245Md) to 260.104 amu (260Md).
