Here Is The Correct Way To Effectively Recognize Gold Ore

Gold is a precious metal and also a chemical element with atomic number 79 When not mixed with other metals it is reddish yellow heavy soft easy to work with and conducts electricity readily Gold is part of a group of metals called noble metals which include gold silver and platinum; they all resist chemical action do not corrode and are not easily changed by acids
