Elemental symbol of magnesium

The elemental symbol of magnesium is Mg.

Magnesium is a metallic chemical element. David of Britain reduced magnesium oxide with potassium to produce metallic magnesium in 1808. Magnesium is a silvery white light alkaline earth metal with active chemical properties, which can react with acid to generate hydrogen, and has certain ductility and heat dissipation. Magnesium is widely distributed in nature and is one of the essential elements for human body.

Magnesium has strong reducibility and can react with boiling water to release hydrogen. Magnesium can react with N2 and O2, so when it burns in air, it will give off dazzling white light, release heat and generate white solid. The change of vinegar is that bubbles come out quickly, float on the vinegar surface and gradually disappear. Some fireworks and flares contain magnesium powder, which makes use of the characteristic that magnesium can emit dazzling white light when it burns in the air. The valence of magnesium in chemical reactions is usually +2.

Application field:

1, medical use: treating magnesium deficiency and spasm.

2. Sports use: inject magnesium compounds a few hours before or after strenuous exercise to make up for the loss of magnesium. Gymnasts often use basic magnesium carbonate to increase friction. Medical treatment: If magnesium salt is injected too quickly, it will cause fever and general malaise.

3. Magnesium is an important material in aviation industry, and magnesium alloy is used to manufacture aircraft fuselage and engine parts. Magnesium is also used to make photographic and optical instruments; Magnesium and its alloys are also widely used in unstructured applications. As a strong reducing agent, magnesium is also used to produce titanium, zirconium, beryllium, uranium and hafnium. Widely used in aerospace technology, aviation, automobiles, instrumentation and other industrial sectors.
