Physical properties of magnesium: silver white luster, slightly ductile. The density of magnesium is small and the ionization tendency is large. In air, a thin oxide film will be formed on the surface of magnesium, making it difficult for air to react with it. Magnesium is a metal element with the symbol Mg.
Daily use of magnesium:
1. Medical use: to treat magnesium deficiency and spasm.
2. Sports use: Inject magnesium compound a few hours before strenuous exercise, or inject it after strenuous exercise to make up for the loss of magnesium. Gymnasts often apply basic magnesium carbonate to increase friction. Medical treatment: If magnesium salt is injected too fast, it will cause fever and general discomfort.
