Brit.

/ˌmɛndəˈliːvɪəm/,

/ˌmɛndəˈleɪvɪəm/, U.S.

/ˌmɛndəˈliviəm/,

/ˌmɛndəˈleɪviəm/

Origin: From a proper name, combined with an English element. Etymons: proper name Mendeleev , -ium suffix.

Etymology: < mendelev-, altered form of the name of Dmitrij Ivanovič Mendeleev (1834–1907), Russian chemist, who was instrumental in the development of the periodic table + -ium suffix. Compare French mendélévium (1959); Russian mendelevij (?1966) is probably < the English word.

Chemistry.

A radioactive metallic chemical element of the actinide series, atomic number 101, which is produced artificially and whose longest-lived known isotope has a half-life of two months. Symbol Md, formerly Mv.

1955 A. Ghiorso et al. in Physical Rev. 98 1519/2 We would like to suggest the name mendelevium, symbol Mv, for the new element in recognition of the pioneering role of the great Russian chemist, Dmitri Mendeleev.

1955 Sci. News 37 117 The element has been named ‘mendelevium’ (symbol, Mv) after the Russian chemist Mendeleev.

1967 New Scientist 21 Sept. 598/2 The new mendelevium isotope, with 101 protons and 157 neutrons, falls into the odd-odd class... The long half-life will enable quite large quantities of mendelevium to be made.

1971 C. Keller Chem. Transuranium Elem. ii. ix. 596 Six isotopes of mendelevium are known with mass numbers 252 and 254–258... They can be produced by the bombardment either of uranium or plutonium with heavy ions, or of einsteinium with α particles.

1993 Guardian 13 July (Educ. section) 17/4 Mendelevium was first detected literally one atom at a time.
