What Is the Chemical Formula for Gold? |
Gold is a highly valued metal that has been known about for roughly 5,500 years. It can sometimes be found on its own, but it is more often found mixed with silver, quartz, lead, zinc and copper. There is also approximately 1 milligram of gold dissolved in every ton of seawater, but it would cost more to extract it than the gold is worth.
