What is Mg? Important knowledge about Mg.

  1. Definition of Mg
    Mg is the symbol for magnesium, a chemical element with the atomic number 12 on the periodic table. Magnesium is an alkaline earth metal, silver-white, ductile and light. Magnesium has an atomic weight of 24.3050 and its atomic structure consists of 12 protons, 12 neutrons and 12 electrons. When forming an ion, magnesium usually loses 2 electrons to form the Mg2+ ion.

  2. Properties of Mg
    2.1 Physical properties of Mg
    At room temperature, magnesium is solid, silver-white, odorless, and does not have a pH level because it does not dissolve in water.
    2.2 Chemical properties of Mg
    Magnesium is highly combustible in air, creating bright white phosphorescent strands, forming oxidized magnesium powder. Magnesium can also react with acids to form magnesium salts and hydrogen.

  3. Common chemical equations involving Mg

  4. Preparation of Mg
    4.1 Laboratory preparation of Mg
    In the lab, there is no preparation process for magnesium because it is very dangerous as magnesium is highly combustible.
    4.2 Industrial preparation of Mg
    Magnesium is prepared industrially through the electrolysis process of magnesium salt solution.
