Unbiquadium (pronounced /ˌʌnbɪˈkwɒdiəm/) is the temporary name of an undiscovered element in the periodic table that has the temporary symbol Ubq and atomic number 124.


The name unbiquadium is used as a placeholder, as in scientific articles about the search for element 124. Transuranic elements (those beyond uranium) are, except for microscopic quantities and except for plutonium, always artificially produced, and usually end up being named for a scientist or the location of a laboratory that does work in atomic physics (see systematic element name for more information).

Likely properties

Since this element is a member of nearby island of stability, it would have isotopes that have long half life, perhaps on the order of tens of thousands of years. The isotope with the longest half life would be Ubq-330, with 124 protons and 206 neutrons.

This element would presumed to be metal and solid, which would probably be silvery white.

The reactivity of unbiquadium is high. Unbiquadium would react violently with water, air, and acids.
