The IUPAC has accepted the following new proposals of the Committee on Nomenclature of Inorganic Chemistry (CNIC) for the names and symbols for the transfermium elements:
101 Mendelevium Md 102 Nobelium No 103 Lawrencium Lr 104 Rutherfordium Rf 105 Dubnium Db 106 Seaborgium Sg 107 Bohrium Bh 108 Hassium Hs 109 Meitnerium Mt
The IUPAC Commission on Nomenclature of Inorganic Chemistry, taking into account the proposals of the Transfermium Workgroup (TWG), has recommended the following names and symbols for the transfermium elements on its session in Balatonfüred (Hungary) on August 31, 1994 (see below, however):
101 Mendelevium Md 102 Nobelium No 103 Lawrencium Lr 104 Dubnium Db 105 Joliotium Jl 106 Rutherfordium Rf 107 Bohrium Bh 108 Hahnium Hn 109 Meitnerium Mt
(This proposal supersedes (?) a previous suggestion: 104 Rutherfordium Rf, 105 Hahnium Ha, 106 Seaborgium Sg, 107 Nielsbohrium Ns, 108 Hassium Hs, 109 Meitnerium Mt.)
See, however, a controversial statement of the discoverers: P. Armbruster, Nachr. Chem. Tech. Lab. 43 (1), 53 (1995); they insist on:
107 Nielsbohrium 108 Hassium 109 Meitnerium
The following preliminary names and symbols have been in use:
104 Unnilquadium Unq 105 Unnilpentium Unp 106 Unnilhexium Unh 107 Unnilseptium Uns 108 Unniloctium Uno 109 Unnilennium Une 110 Ununnilium Uun 111 Unununium Uuu
According to WebElements by Mark Winter, names are as follows (May 1997):
104 rutherfordium Rf 105 dubnium Db 106 seaborgium Sg 107 bohrium Bh 108 hassium Hs 109 meitnerium Mt
