I'm a little surprised. As an adult, I always think that gold is more expensive than silver. But why? I really didn't sum it up. I thought for a moment and said,' Because gold is rarer than silver, the density of gold is higher than that of silver, and oh, it is linked to the US dollar, which can represent currency and can be used for circulation.' I'm sure what I said then was definitely not as coherent as what I write now. I still have complaints about this problem.
So, I decided to check the relevant statements, sum up the general situation and let the children know.
Regarding gold and silver, the reasons why gold is more expensive than silver are as follows.
1. rarity: gold, silver and platinum are all called precious metals by us. Because they are indeed more expensive than copper, iron and aluminum. One of the reasons for being expensive is scarcity. Among them, gold is the rarest variety in the earth's crust, and the measurement unit of element abundance is that three precious metals (gold, silver and platinum) are the rarest (only 0.004ppm), followed by platinum (0.005ppm) and silver (0.075ppm). So in terms of rarity, gold is the most expensive.
2. Historicity: Ancient gold and silver were circulated as money. Since ancient times, gold is more valuable than silver.
Modernity: Gold is not only used for jewelry circulation, but also a financial asset. As a financial asset, all countries in the world have gold reserves. Gold reserve refers to the gold held by a country's monetary authorities to balance the international payments and maintain or influence the exchange rate level, and is held as a financial asset. It plays a special role in stabilizing the national economy, curbing inflation and improving international reputation. Every country must reserve gold assets. This is also a measure of a country's wealth, and it is also the last guard and reserve of a country. So this also reflects the uniqueness of gold.
4. Value preservation: Gold is a reliable means of value preservation. Gold has relative inherent stability relative to paper money. Comparative paper money can be printed at any time, while natural pure gold is very scarce. Although 3D gold can be extracted by technology now, it is not as valuable as natural pure gold. 3D gold is mostly used for jewelry processing.
