Unhexquadium is a radioactive element that has yet to be discovered. It has (or will have, when it’s discovered) 164 protons and 318 neutrons. Theoretical interest in the chemistry of unhexquadium is largely motivated by theoretical predictions that it, especially the isotope 482Uhq (with 164 protons and 318 neutrons), would be at the center of a hypothetical second island of stability (the first being centered on 306Ubb).[1][2][3]
