WebSlamming neon (element 10) into uranium, for example, yields nobelium (102). But the odds of fusion (and survival) decrease markedly as atoms grow heavier because of increased repulsion between the positively charged nuclei, among other factors. Creating most elements in the superheavy realm (beyond 104) therefore requires special tricks.
