mendelevium
n 1: a radioactive transuranic element synthesized by bombarding
einsteinium with alpha particles (Md is the current symbol
for mendelevium but Mv was formerly the symbol) [synonym:
{mendelevium}, {Md}, {Mv}, {atomic number 101}]

mendelevium \men*de*le"vi*um\ (m[e^]n*d[e^]*l[=e]"v[=e]*[u^]/m),
a. [From Dmitri Mendeleyev, discoverer of the periodic law.]
(Chem.)
an unstable radioactive element discovered in 1955 and
produced artificially only in very small quantities; symbol
Md (also Mv). It is a transuranic element with atomic number
101. Isotopes 255, 256, 257, and 258 have been prepared.
Md258, the longest-lived, has a half-life of two months.
