Mendelevium is named after Dmitri Mendeleev, creator of the periodic table. It was the first element to be produced one atom at a time.

About Mendelevium

Detection of mendelevium was achieved one atom at a time, the first element for which that technique was necessary and the method that has governed superheavy element work ever since. The name honours Dmitri Mendeleev, whose periodic table furnished the framework into which such elements are placed. Mendelevium carries atomic number 101 and a relative atomic mass of 258.0, with the configuration [Rn] 5f13 7s2 and an electronegativity of 1.3, and it is a solid at standard temperature and pressure. Because it must be produced by accelerator bombardment rather than reactor irradiation, the quantities available have never exceeded what can be studied by tracer and single-atom chemical techniques.
