Gold is the only yellow metal. All other metals darken or turn a yellowish colour after they have oxidised or reacted with other chemicals. Gold is one of the heaviest and densest of all metals in the Periodic Chart; a cubic foot would weigh more than half a ton. Pure gold will melt at 1064.43° and boils at 2856.1°.The unique colour and shine, combined with the fact it doesn't tarnish, gave gold a unique edge over other metals and the rarity installed confidence because people could have faith it would hold its value as the difficulty in mining gold meant no-one could try to devalue the metal as a currency.
Why is gold so rare : Gold is rare throughout the Universe because it's a relatively hefty atom, consisting of 79 protons and 118 neutrons. That makes it hard to produce, even in the incredible heat and pressure of the 'chemical forges' of supernovae, the deaths of giant stars responsible for creating most chemical elements.
What’s special about gold
It is attractive in colour and brightness, durable to the point of virtual indestructibility, highly malleable, and usually found in nature in a comparatively pure form. The history of gold is unequaled by that of any other metal because of its perceived value from earliest times.
Why is gold so interesting : Gold is rare and difficult to extract. Gold is malleable and can be formed as needed for use in, among others, electronics, dentistry, medical tools, and the defense, aerospace, and automotive industries. Gold is durable and noncorrosive. Gold has visual beauty and magnetic appeal.
As the rarest of the platinum group metals, rhodium occurs at roughly 0.000037 parts per million in the Earth's crust, while gold is found at an abundance of around 0.0013 parts per million, according to the Royal Society of Chemistry.
Real gold doesn't burn or get darker when heat is applied. If the piece of gold is real, the heat will melt the gold which is why gold can be molded and formed into different shapes without losing its color.
Why is there no 100% gold

999 gold is considered the best purity of gold readily available, and is described as being 24 carat. This refers to purity in parts per 1,000 – known as fineness – meaning 999 parts are gold. Pure gold is soft and malleable, making it impractical for many applications.The difference is that 9999 gold represents Gold that is more refined. The meaning of refined gold is that it is pure and has few impurities. When gold is measured, it is measured by numbers and usually does not pass through three digits.
