1. First, let's draw a gold ingot. The shape of the ingot is pointed at two ends and convex in the middle.

2. Then draw an ingot beside it. The second ingot can be slightly smaller, and the drawing method is still the same.

3. Draw another expression on the ingot. Note that expressions can be drawn differently, and cute cartoon ingots will be drawn.

4. Finally, color painting. We color the gold ingot, paint the edge dark yellow, and then paint the blush, and the cartoon stick figure of the ingot is completed.

Gold is a transition metal, which can form +3 and+1 valence compounds. Gold is chemically inactive, but it can be corroded by chlorine, fluorine, aqua regia and cyanide. Gold can be dissolved by mercury to form gold amalgam; Nitric acid that can dissolve silver cannot dissolve gold. The above two properties become the basis of gold refining technology, which are called "adding silver to divide gold" and "separating gold from silver" respectively.

Gold is a very precious metal and has a wide range of uses. Because of its excellent characteristics, gold has been used as currency in history. Gold can be used for commodity trading. It is precisely because of the color characteristics and ductility of gold itself that gold is also widely used to make jewelry. Historically, dignitaries like to wear gold and silver.

And this habit has continued to this day. Moreover, because of its inert chemical properties, strong corrosion resistance and good electrical and thermal conductivity, gold is also widely used in modern high-tech industries, such as electronic technology, communication technology, aerospace technology, chemical technology, medical technology and so on.
