Gold, a shiny, yellow metal, is an element, meaning it's made of just one kind of atom. This element is created in the universe's most dramatic events: explosions of stars called supernovae and when neutron stars crash into each other. These cosmic events produce gold atoms that get spread out across space.

Gold (Au) is a chemical element with the atomic number 79 and the symbol Au, derived from the Latin word "aurum". It is a precious metal and is known for its unique properties, including: Malleability and ductility: Gold is highly malleable, which means it can be hammered into thin sheets without breaking.
DetailsThe other possibility is a colloidal solution, with solid nanoparticles of gold dispersed throughout hydrothermal and geothermal fluids. Since the gold nanoparticles hold a charge (like milk fat), they repel each other. When the charge breaks down, the gold particles clump together in a process similar to coagulation, known as flocculation.

Pyrite has a higher specific gravity measuring 4.8-5.0, while gold weighs in at 19.3 g/cm3. Even though gold has a higher mass, pyrite's relative density exceeds that of gold due to the presence of sulfur in its molecular structure. So by volume, a piece of pyrite weighs more than the same volume of gold.
