Here Is The Correct Way To Effectively Recognize Gold
2018-12-7 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.
