That means r varies as A 1 / 3, so ( Z 2 / r 3) = K = ( Z 2) / A. K is called a "fissility parameter." A given value of K defines a set of nuclei which have similar liquid-drop-model barriers against spontaneous fission.

The quest for new elements is usually described using atomic numbers. As of 2024, all elements with atomic numbers 1 to 118 have been observed. Synthesis of new elements is accomplished by bombarding target atoms of heavy elements with ions, such that the sum of the atomic numbers of the target and ion elements equals the atomic number of the element being created. In general, the half-life of a nuclide becomes shorter as atomic number increases, though undiscovered nucli…
