At atomic number 101, mendelevium was a different type of element: the first of the trans-fermium elements. But to make it, Seaborg employed the same piece of equipment - the particle accelerator that had been used to chemically identify plutonium after it was discovered by Enrico Fermi during the Second World War. read more
Mendelevium has 14 recognized isotopes. The most stable one is 258 Md, which has a half-life of about 51.5 days. Sources of mendelevium. Mendelevium is artificially produced, and it has never been made in great quantities. Uses of mendelevium. Only small quantities of mendelevium have ever been produced, so it has no commercial uses. read more
Mendelevium is a synthetic element with chemical symbol Md (formerly Mv) and atomic number 101. A metallic radioactive transuranic element in the actinide series, it is the first element that currently cannot be produced in macroscopic quantities through neutron bombardment of lighter elements. read more
