Magnesium physical properties:
Magnesium is a light metal with an atomic number of 12 and a relative atomic mass of 24.31, belonging to the second period element. The following are some physical properties of magnesium:
1. Density: The density of magnesium is 1.738g/cm3, twice that of aluminum. This has led to the widespread use of magnesium in many fields, such as aerospace and automobile manufacturing.
2. Melting point and boiling point: The melting point of magnesium is 651 degrees Celsius and the boiling point is 1107 degrees Celsius. This means that magnesium retains its stability at high temperatures.
3. Relative atomic mass: The relative atomic mass of magnesium is 24.31. This makes magnesium have special chemical properties in chemical reactions.
4. Conductivity: Magnesium is a good conductive metal. Magnesium has a very low resistivity at room temperature and can be used to make electrical equipment such as wires and cables.
5. Magnetism: Magnesium is a paramagnetic material, that is, it will be magnetized under the action of an external magnetic field. Magnesium, however, is very weakly magnetic and difficult to detect.
6. Crystal structure: The crystal structure of magnesium is a closely packed cubic system. This structure gives magnesium a high degree of mechanical strength and good corrosion resistance. In conclusion, magnesium is an important metal element with many excellent physical properties, which makes it widely used in many fields.
