Gold is a chemical element, a transition metal and inert (doesn’t react with almost anything). Its atomic number is 79, meaning it is one of the heavier chemical elements that was formed in the last stages of a dying star, the supernova. This is where pressure and heat is so intense that the elements heavier than iron are formed in the explosion.
On earth gold comes in a variety of forms such as nuggets or in veins in rock. Since its discovery by mankind, it has been revered as a precious metal. It is relatively rare on earth compared to other metals, so was used for things of high value such as currency and for nobility and royalty as well as in arts and architecture.
In the modern era in monetary policy, gold was the backbone of currency known as the gold standard. However this system was abandoned in favour of fiat currency which is the current monetary system. This means that the money in circulation isn’t backed by any kind of physical commodity (like gold), it is essentially made out of nothing.
