The Science of Why Gold is Money

We all know that much of what makes gold the world’s pre-eminent money is its scarcity and hence it’s intrinsic value.  Never before is that trait so prevalent as this world of rampant money printing (via QE), record negative interest rates and near zero everywhere else, hyper-inflation in multiple emerging economies and an ensuing economic social divide (1% v ‘the rest’) of historic proportions.  None of this is news to regular followers.  However few probably know the chemistry behind gold’s pre-eminence. Visual Capitalist have a knack for presenting things visually and insightfully and just published their latest piece titled “Why Gold is Money: A Periodic Perspective” presenting a chemist’s breakdown of the periodic table and why gold is money.  If the GIF image below doesn’t move for you, click on this link to see it ‘play’ for you and/or read the text below walking you through it.

“Why Gold is Money

The economist John Maynard Keynes famously called gold a “barbarous relic”, suggesting that its usefulness as money is an artifact of the past. In an era filled with cashless transactions and hundreds of cryptocurrencies, this statement seems truer today than in Keynes’ time.

However, gold also possesses elemental properties that has made it an ideal metal for money throughout history.

Sanat Kumar, a chemical engineer from Columbia University, broke down the periodic table to show why gold has been used as a monetary metal for thousands of years.

The Periodic Table

The periodic table organizes 118 elements in rows by increasing atomic number (periods) and columns (groups) with similar electron configurations.

Just as in today’s animation, let’s apply the process of elimination to the periodic table to see why gold is money:

Gases and Liquids

Noble gases (such as argon and helium), as well as elements such as hydrogen, nitrogen, oxygen, fluorine and chlorine are gaseous at room temperature and standard pressure. Meanwhile, mercury and bromine are liquids. As a form of money, these are implausible and impractical.

Lanthanides and Actinides

Next, lanthanides and actinides are both generally elements that can decay and become radioactive. If you were to carry these around in your pocket they could irradiate or poison you.

Alkali and Alkaline-Earth Metals

Alkali and alkaline earth metals are located on the left-hand side of the periodic table, and are highly reactive at standard pressure and room temperature. Some can even burst into flames.

Transition, Post Transition Metals, and Metalloids

There are about 30 elements that are solid, nonflammable, and nontoxic. For an element to be used as money it needs to be rare, but not too rare. Nickel and copper, for example, are found throughout the Earth’s crust in relative abundance.

Super Rare and Synthetic Elements

Osmium only exists in the Earth’s crust from meteorites. Meanwhile, synthetic elements such as rutherfordium and nihonium must be created in a laboratory.

Once the above elements are eliminated, there are only five precious metals left: platinum, palladium, rhodium, silver and gold. People have used silver as money, but it tarnishes over time. Rhodium and palladium are more recent discoveries, with limited historical uses.

Platinum and gold are the remaining elements. Platinum’s extremely high melting point would require a furnace of the Gods to melt back in ancient times, making it impractical. This leaves us with gold. It melts at a lower temperature and is malleable, making it easy to work with.

Gold as Money

Gold does not dissipate into the atmosphere, it does not burst into flames, and it does not poison or irradiate the holder. It is rare enough to make it difficult to overproduce and malleable to mint into coins, bars, and bricks. Civilizations have consistently used gold as a material of value.

Perhaps modern societies would be well-served by looking at the properties of gold, to see why it has served as money for millennia, especially when someone’s wealth could disappear in a click.”

Now altogether, lets sing… “Hydrogen, Helium, Lithium, Beryllium… Boron….”.  Some songs never leave your head.  How far through it can you still get?
