Unbinilium (IPA: /ˌʌnbɪˈnɪliəm/), also called eka-radium, is the temporary name of an undiscovered chemical element in the periodic table that has the temporary symbol Ubn and has the atomic number 120.

The name unbinilium is used as a placeholder, as this element hasn't been officially named. Transuranic elements are, except for microscopic quantities, always artificially produced.

See systematic element name.

The element is of interest because it is part of the hypothesized island of stability, with isotope 318 being the most stable of those that can be created by current methods. Using the spherical model of shell formation, element 120 would be the heaviest element in an island of stability, and also, along with 114, the most spherical. (Patra et al. Journal of Physics 2000)

Unbinilium would be highly reactive as this element is a member of Alkaline earth metals. It would be much more reactive than any other lighter elements of this group. This element would react violently in air to form unbinilium oxide and in water to form unbinilium hydroxide, which would be a strong base.
