the periodic table
The periodic table of elements was a list of chemical elements sorted according to the number of nuclear charges of the elements. It was generally rectangular in shape, with seven horizontal rows (called periods, where the number of atomic electrons of the same period element was the same, and the atomic number increased from left to right) and 18 vertical rows (called families, which had the same or similar structure of the electron layer, divided into main family, sub-family, and zero family). 118 elements have been discovered, of which 94 are natural elements and the rest are synthetic elements in the laboratory. In 1789, the French mathematician Lavoisier grouped 33 known elements into gases, metals, non-metallic minerals, and rare earths to form the first elemental classification table. In 1869, the Russian mathematician Mendelev summarized and published the first generation of the periodic table of elements. After that, there were rings, cubes, columns, buildings, spirals, lemniscus, octagonal pyramids, spheres, and triangular-shaped periodic tables. These substitutes were mostly developed to highlight or emphasize the chemical or physical properties of the elements. The periodic table of elements was widely used to infer the general properties of elements, find new materials, find or artificially synthesize new elements, and also to find mineral sources and determine whether they could be used as a catalyst. In addition, the names of the elements in the periodic table had different characteristics in different languages. For example, the Chinese names of the elements had a corresponding word for each element. The radical represented the classification (free translation), and the radical represented the pronunciation (English translation). Compared to the Western language, it was more advantageous to remember. The Chinese periodic table of the elements could even be composed into songs for easy memorization. In terms of element collection, the radioactive elements in the periodic table (such as polinium, radon, Fransium, etc.) had a short half-life. The nucleus would decay and release high-energy particles and electromagnetic waves, which were harmful to humans. Collecting them was not only expensive but also fatal. There were also some elements (such as astine) that had low reserves and were unstable. Collecting 1 gram was almost impossible. "The Island of Life" is also a wonderful novel.

The practical application of the periodic table
The periodic table of elements had a wide range of practical applications in many fields: 1. ** Predicting the properties of elements and their compounds **: Through the position of elements in the periodic table, one can infer their highest positive valency, lowest negative valency, intermediate valency, and the properties of the highest and highest valency corresponding to the hydrates. One can also compare the ion radius, ion reduction, and so on. For example, in the fourth cycle VII A group, the highest positive valency of the element could be obtained as +7, and the lowest negative valency was-1. 2. Materials Science: Helping scientists design better materials. A deep understanding of the periodic table of elements could be used to prepare materials with special properties, such as rigid ceramic, elastic materials, etc. These materials could be used in electronic equipment, energy, aerospace, and other fields. 3. ** Medicinal Chemistry **: Medicinal pharmacists apply the periodic table knowledge in the research and development of drugs. Understanding the chemical properties of different elements and the structure of compounds could help develop safer and more effective drugs. 4. ** Geochemistry research **: Due to the regular distribution of elements on the Earth, geologists can understand the evolution process and environmental changes of the Earth through in-depth study of the periodic table, analysis of the elements 'neutrons, distribution, and transformation methods. 5. [Chemistry laboratory work: It is an important basic tool for a pharmacist in the laboratory.] With the help of the periodic table, a pharmacist could quickly and accurately understand the relationship between elements, analyze the reaction process, and prepare chemicals. 6. ** Predicting the chemical properties and reaction activity of elements **: provides a framework for predicting the physical and chemical properties of elements. The position of the surrounding elements in the periodic table could be used to infer the charge and radius of an element and the stability of the compound. This was crucial in the research of new materials and drugs. In addition, it could also predict the reaction activity of the element, that is, the reaction of the element with other elements or molecules. Usually, the element with a small atomic number was more active and sensitive, while the element with a large atomic number was relatively stable. 7. [Search for specific substances: Can be used to find materials for the manufacture of semiconductor materials, pesticide materials, as well as catalyst, high-temperature and corrosion-resistant alloy materials.] 8. ** Industrial production **: In addition to the wide application of metal elements such as copper, aluminum, lead, etc., non-metallic elements can be used to make soap, plastic, glass, etc. Inert gases have important applications in the fields of semiconductor, light bulb technology, aerospace technology, etc. The novel " Primitive Law " is equally exciting.

periodic table of chemical elements
The periodic table of chemical elements was a list of chemical elements sorted according to the number of nuclear charges of the elements. It was generally rectangular, with seven horizontal rows (called periods) and 18 vertical rows (called families, including the main family, sub-family, and zero family). In the same period, the number of electron layers of each element's atom is the same, and the atomic number increases gradually from left to right. The same element has the same or similar structure of the electron layer. 118 elements have been found in the periodic table, of which 94 are natural elements and the rest are synthesized in the laboratory. The number of elements in each period was different. It could be divided into extremely short periods (the first period, two elements), short periods (the second and third periods, eight elements each), long periods (the fourth and fifth periods, eighteen elements each), and very long periods (the sixth and seventh periods, thirty-two elements each). The development of the periodic table of elements had gone through many stages. In 1789, the French pharmacist Lavoisier first grouped the known 33 elements into a classification table. In 1869, the Russian pharmacist Mendelev summarized and published the first generation of the periodic table of elements. Later, many types of periodic tables were proposed, such as rings, cubes, and other shapes to highlight the different properties of the elements. The periodic table had many applications. It could be used to deduce the general properties of elements, find new materials, find or synthesize new elements, find mineral sources, and determine whether they could be used as a catalyst. The relevant knowledge points included the law of elemental properties changing with the cycle, such as the change of radius, valency, metalicity, and non-metalicity (when describing elements, metalicity and non-metalicity were used. When describing simple substances, reduction and oxidization were used, but the essence was the ability to gain and lose electrons). In addition, there were methods to memorize the periodic table of elements, as well as information about the prices of the elements in the periodic table. For example, the most expensive natural element was Fransium (the cost of laboratory production was extremely high), the most expensive natural element that could be bought was Lutesium, the most expensive synthetic element was Uranium, and there were also some cheap and common elements such as copper, sulfur, and carbon.
