  2. Mendelevium - Wikipedia

    • Mendelevium is a synthetic chemical element; it has symbol Md (formerly Mv) and atomic number 101. A metallic radioactive transuranium element in the actinide series, it is the first element by atomic number that currently cannot be produced in macroscopic quantities by neutron bombardment of lighter elements. It is the third-to-last actinide and the ninth transur… See more

    Discovery

    Mendelevium was the ninth transuranic element to be synthesized. It was first synthesized by Albert Ghiorso,
    To … See more

    Characteristics

    In the periodic table, mendelevium is located to the right of the actinide fermium, to the left of the actinide nobelium, and below the lanthanide thulium. Mendelevium metal has not yet been prepared in bulk quantities, … See more

    Production and isolation

    The lightest isotopes ( Md to Md) are mostly produced through bombardment of bismuth targets with argon ions, while slightly heavier ones ( Md to Md) are produced by bombarding plutonium and americium targets with ions of … See more

    Toxicity

    Though few people come in contact with mendelevium, the International Commission on Radiological Protection has set annual exposure limits for the most stable isotope. For mendelevium-258, the ingestion limit was set at … See more
