Mendelevium is an artificial chemical element, radioactive, unstable, metal, actinoid, atomic number 101. Mendelevium is available only of amounts of femtograms; with these quantities a detailed chemical study is not possible. Having a Pauling electronegativity of 1,3 Md is a reactive element. Valences are 2 and 3; not surely confirmed 1.
Fluorides, hydroxides etc. of Md were observed.
The estimated melting point is 827 0C.
The estimated atomic radius is 194 pm.
The estimated first ionization energy is 635 kJ/mol.
