What is Mercury?

With the progress of science and technology and the development of society, chemical products have invariably permeated our daily lives, in medicine, food, cosmetics, electronics, industry, and other areas, becoming an essential part of our lives. One such product is Mercury which has developed particularly rapidly in recent years. Do you know about Mercury?
The official answer: (Hydrargyrum) is a chemical element, element symbol Hg, the 80th position of the periodic table, in the periodic table of chemical elements located in the 6th cycle, the IIB group, known as mercury, as well as “white, feminine, 澒, shen gum, yuanshui, lead essence, flow beads, yuanzhu, red mercury, sand mercury, spirit liquid, living treasure, Ziming” and other alternative names, is the only metal at room temperature and atmospheric pressure in the liquid state (in the strict sense, gallium (symbol Ga, element 31) and cesium (symbol Cs, Element 55) is also liquid at room temperature (29.76 °C and 28.44 °C). Mercury is a silvery-white shiny heavy liquid that is stable and insoluble in acids or bases. Mercury evaporates at room temperature, and mercury vapor and mercury compounds are toxic (chronic). Mercury use has a long history and is used. In medieval alchemy, together with sulfur and salt, it was called the sacred three elements of alchemy.

What’s the application of Mercury?

The most used applications are in the manufacture of chemicals for industrial use and in electronic or electrical products. Mercury is also used in thermometers, especially in thermometers that measure high temperatures. More and more gaseous mercury is still used to make fluorescent lamps, and many other applications have been phased out due to health and safety issues, replaced by less toxic but much more expensive Galinstan alloys. Besides, mercury uses include:
Gold can be broken down from its minerals and is thus often used in gold mines.
It is used to make instruments such as barometers and diffusion pumps.
Gaseous mercury is used in mercury vapor lamps.
Used in the manufacture of liquid mirror telescopes. Telescopes that use rotation to form a parabolic shape of the liquid as the main mirror for astronomical observations are one-third the price of ordinary telescopes.
Other uses: mercury switches, pesticides, processes in the production of chlorine and potassium hydroxide, preservatives, acting as electrodes, batteries and catalysts in some electrolytic equipment.
