Noun
a transuranic element
Source: WordNetChemistry experiments have confirmed that seaborgium behaves as the heavier homologue to tungsten in group 6. The chemical properties of seaborgium are characterized only partly, but they compare well with the chemistry of the other group 6 elements. Source: Internet
The only other oxidation state known for seaborgium other than the group oxidation state of +6 is the zero oxidation state. Source: Internet
The twelve isotopes of seaborgium have half-lives ranging from 92 microseconds for 261 Sg to 3.1 minutes for 269 Sg. Source: Internet
Thus, bombardment of 248 Cm with oxygen ( 18 O) or magnesium ( 26 Mg) yielded certain isotopes of seaborgium ( 265 Sg) and hassium ( 269 Hs and 270 Hs). Source: Internet
