Can gold be created from other elements?

May 02, 2014In principle, we can therefore create gold by simply assembling 79 protons (and enough neutrons to make the nucleus stable). Or even better, we can remove one proton from mercury (which has 80) or add one proton to platinum (which has 78) in order to make gold. The process is simple in principle but hard to do in practice.
