Mendelevium is a chemical element, having the chemical symbol Md. Its atomic number (the number of protons) is 101. It has a standard atomic weight of 258 g•mol −1 and it is a solid in its elemental form.
Medelevium is considered a member of the "Transuranic" class of elements. At a pressure of 101.325 kPa, it has a melting point of 827 °C. There is no data available regarding its boiling point.
It was named after Dmitri Ivanovich Mendeleev, who is recognized as the father of the Periodic table of elements.[1]
