The first isotope of mendelevium (Es-256) was obtained in 1955 bombarding einsteinium-253 with alpha particles:
Es-253(alpha)Md-256 + n
As a radioactive element mendelevium is dangerous.
Mendelevium has a half life of 51 days and is not a natural element but is in fact made as well as the fact that Mendelevium in large masses can be harmful to humans because it is a radioactive metal.
The chemistry of mendelevium is practically unknown today.
Mendelevium is supposed to have a gray metallic appearance.
Mendelevium hasn't uses now.
Mendelevium is an artificial element obtained only in infinitessimal quantities.
Mendelevium was obtained in 1955 after the bombardment of 253Es with alpha particles in a cyclotron.

Mendelevium was first obtained by Glenn Seaborg, Stanley Thompson, Albert Ghiorso, Bernard Harvey, Gregory Choppin in 1955, in USA.
Mendelevium was discovered in 1955 by a University of California by hitting Einsteinium with helium ions.

It is impossible to measure the hardness of a metal obtained only in extremely ultratraces quantities.
Mendelevium has not uses.
