The ultimate alchemy: directly editing an element's identity by changing the number of protons in its nucleus. This isn't just nuclear fusion or fission (smashing nuclei together or splitting them apart); it's the precise, surgical addition or removal of protons to transmute one element into another on demand. Lead into gold? Basic. Turning toxic waste into inert helium, or synthesizing stable, super-heavy elements unknown in nature? That's the goal. It requires staggering amounts of energy and control over the strong nuclear force, making it the pinnacle of material science—literally rewriting the periodic table to suit your needs.
*Example: "The waste cleanup used atomic number engineering. They ran the radioactive cesium-137 through a proton scrubber, yanking out protons one by one until it became stable, harmless platinum. The process cost a billion dollars in antimatter catalyzed energy, but hey, free jewelry."*
