Unhexquadium is a radioactive element that has not been discovered. It will have 164 protons and 318 neutrons . Interest in the chemistry of unhexquadium is largely prompted by predictions that the isotope 482 Uhq (with 164 protons and 318 neutrons ), would be at the center of a possible second island of stability (the first being centered on 306 Ubb or 298 Fl ).[ 1] [ 2] [ 3]
