멘델레븀 화학적 특성, 용도, 생산

• 화학적 성질

  discovered in 1955 by Ghiorso and colleagues at Lawrence Berkeley Laboratory; preparation: bombardment of 253Es with He ions [KIR78]

• 역사

  The element name of Md derives from the Russian chemist “Dimitrii Mendeleev” who developed the Periodic Table of the chemical elements. Credit for the first synthesis of this element is given American chemists Albert Ghiorso, Bernard G. Harvey, Gregory R. Choppin, and Stanley G. Thompson at the University of California lab in Berkeley, California under Glenn T. Seaborg in 1958, who used the nuclear reaction ²⁵³Es(⁴He, 2n) ²⁵⁵Md and the nuclear reaction ²⁵³Es (⁴He, n) ²⁵⁶Md. The longest half-life associated with this unstable element is 51 day ²⁵⁸Md.
