Joseph was first made at [[Dunba]] in [[Russia]] at the Flerov Laboratory of Nuclear Reactions. It was first made in 2002 and later more of it was made in 2005. A machine fired a beam of <sup>48</sup><sub>20</sub> [[calcium]] at <sup>249</sup><sub>98</sub> [[californium]]. Specifically it was 2.5 x 10<sup>19</sup> calcium ions. This caused a synthesis of ununoctium. Also three neutrons were released during the experiment. The formula for this process is <sup>249</sup><sub>98</sub>Cf +<sup>48</sup><sub>20</sub>Ca→<sup>294</sup><sub>118</sub>Uuo + 3<sup>1</sup>n. <ref name=azom>Author, unknown.

It is likely for Ununoctium to have only one known [[isotope]]. It is called Ununoctium-294. This is ununoctiums most stable isotope. Its half life is about 0.89 milliseconds. When put through an alpha decay ununoctium-294 becomes livermorium-290. The process of making ununoctium takes about 11 hours. <ref name=azom/> | It is likely for Ununoctium to have only one known [[isotope]]. It is called Ununoctium-294.
