Before going through the chemical properties, let us have a look at the physical properties of gold. Gold is ductile as well as malleable in nature. This means it can be drawn into wires and beaten into thin sheets. This soft metal is able to reflect heat as well as light. Gold is a metal and therefore a good conductor of electricity.

Physical Properties of Diamond Published by Travis Wade on May 23, 2020 May 23, 2020. Diamond is the hardest of all natural materials. The hardness of any given material is usually determined by pressing a carefully shaped indenter onto a surface under a load, resulting in a permanent plastic deformation. The indenter must be at least as hard ...

Only a metal has these two properties. Gold has a very high value per ounce (gram) or per cubic inch (milliliter); a lot of value is stored in something that is both light and compact. Few metals have a value density anywhere near gold. For example, one would need about 60 ounces of silver today to hold the same value as one ounce of gold.
