Explanation:

Gold is a soft, precious yellow metal that, unlike other metals, is very resistant to chemical influences (mainly air and water - in layman's terms, gold does not rust ...) it dissolves only in royal water (a mixture of concentrated nitric and hydrochloric acid ) and in potassium solution.

It is characterized by high gloss, thermal and electrical conductivity, extensibility, and formation. When you first touch the gold, you will definitely notice that the gold object is unusually heavy due to its size. The characteristic feature of gold is its high density, 19 times higher than water, 2.5 times higher than iron or copper, almost twice as high as silver or lead.
