Unbiseptium
hypothetical chemical element with the atomic number 127
Unbiseptium /ˌuːnbaɪˈsɛptiəm/, also called eka-americium,[source?]er 127 and symbol Ubs. It comes immediately after unbihexium, element 126, which is expected to be the most stable element on an island of stability.
Naming
changeThe name unbiseptium is a systematic element name, used as a placeholder until its discovery is confirmed. Transuranium elements beyond californium are always created artificially, and the element usually ends up being named for a scientist or a laboratory that does work in atomic physics.[source?]
Synthesis of unbiseptium
changeUnbiseptium has had one failed attempt at synthesis in 1978 at the Darmstadt UNILAC accelerator by bombarding a natural tantalum target with xenon ions.[1]
