Unbinilium, with the temporary symbol Ubn and atomic number 120, is a synthetic element that has not yet been observed in significant quantities. As of my last knowledge update in October 2023, no isotopes of unbinilium have been definitively produced and studied, primarily due to the challenges associated with synthesizing superheavy elements.
Ununennium is the temporary systematic element name for element 119 in the periodic table, which is currently not yet discovered or observed. It is a synthetic element predicted to belong to the group of alkali metals. Since ununennium has not been synthesized, there are no known isotopes or empirical data about its isotopes. However, theoretical predictions suggest that ununennium would possess several isotopes, like many other elements, based on its potential nuclear configurations.
Uranium has several isotopes, but the most significant ones are: 1. **Uranium-238 (U-238)**: This is the most abundant isotope of uranium, comprising about 99.3% of natural uranium.
