How are elements heavier than uranium made

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. Web17 de out. de 2012 · The first element heavier than uranium was identified in 1940 at the University of California at Berkeley. This was element 93, christened neptunium after the planet Neptune, given that uranium had been named after Uranus in 1789. Neptunium quickly decays into plutonium, atomic number 94, the discovery of which was kept secret …
