Gold is a metal and therefore falls under the branch of chemistry known as inorganic chemistry.

Here's why:

* Inorganic chemistry studies the properties and reactions of all elements except carbon and its compounds (which are the domain of organic chemistry).

* Gold is a naturally occurring element with unique properties like its high electrical conductivity, resistance to corrosion, and its beautiful luster.

While gold is a fascinating element with applications in various fields, its basic chemical properties are studied within the framework of inorganic chemistry.
