Magnesium is a chemical element with the symbol Mg. It is placed in group 2, period 3 of the periodic table. The atomic number of magnesium is 12. This means that magnesium has 12 protons in its nucleus. Magnesium is a solid phase at room temperature and pressure. The melting point of magnesium is about 650°C, and the atomic mass of magnesium is 24, which is in the s block of the periodic table. Magnesium and other elements in this group are considered alkaline earth metals. This is because the oxides they form have fundamental properties, the electronegativity of magnesium is about 1.31, and the atomic radius of magnesium is about 160pm. Magnesium is mainly found in mineral deposits, such as dolomite and magnesite. Seawater also has large amounts of dissolved magnesium ions, a metal that has a wide range of applications, particularly in aircraft design and automobile design.
