Can gold be created from other elements? Science
May 02, 2014· Gold is the chemical element with 79 protons in each atomic nucleus. Every atom containing 79 protons is a gold atom, and all gold atoms behave the same chemically. In 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 mercurySolved: Iron Pyrite, Commonly Known As "fools Gold" Is 46,Iron Pyrite, commonly known as "fools gold" is 46.5% Fe and 53.5% S. a.)
