Magnesium is the 12th in the periodic table of elements. It is a silver-white light alkaline earth metal with active chemical properties, which can react with acid to generate hydrogen gas, and has certain ductility and heat dissipation. Magnesium is widely distributed in nature and is one of the essential elements for the human body.
The periodic table of chemical elements is a list of chemical elements sorted according to the number of nuclear charges from small to large. The list is generally rectangular, and there are spaces in some element periods, so that elements with similar characteristics are grouped in the same group, such as alkali metal elements, alkaline earth metals, halogen elements, rare gases, etc. This enables the formation of element divisions in the periodic table and is divided into seven main groups, seven subgroups, VIII groups, and O groups. Because of its ability to accurately predict the properties of various elements and their relationships, the periodic table is widely used in chemistry and other sciences as a useful framework for analyzing chemical behavior.
