Can copper be turned into gold? For centuries, alchemists pursued this dream, unaware that such a transformation requires a nuclear reaction. In contrast, graphite—the material found in pencil tips—and diamond are both composed entirely of carbon atoms; the key difference lies in how these atoms are arranged. Converting graphite into diamond requires extreme temperatures and pressures to break and reform chemical bonds, making the process impractical. Can copper be turned into gold?
