Special Topic on Table of Chemical Elements

The periodic table of chemical elements is a list of chemical elements ordered from smallest to largest atomic number. The list is generally rectangular, with spaces left in the periods of some elements so that elements with similar properties can be grouped into the same group, such as halogens, alkali metal elements, noble gases, radioactive elements, etc. This creates partitions of elements in the periodic table. Because the periodic table accurately predicts the properties of various elements and their relationships, it is widely used in chemistry and other sciences as a useful framework for analyzing chemical behavior. The modern periodic table was created by the Russian chemist Mendeleev in 1869 to show the periodicity of the properties of the elements known at the time. Since then, the appearance of the periodic table has changed and expanded with the discovery of new elements and the development of theoretical models.
