Magnesium has an excellent strength-to-weight ratio, making it valuable in transportation and aerospace industries.
Burning magnesium produces an intense white light that was once used in photography flash lamps.
Magnesium is the central atom in chlorophyll molecules. Without magnesium, plants could not perform photosynthesis.
Magnesium helps muscles, nerves, bones and the heart function properly. It is an essential nutrient for humans.
Researchers are developing advanced magnesium alloys for electric vehicles, aerospace structures and biomedical implants.
Magnesium is formed inside stars through nuclear fusion. Astronomers detect magnesium in stars and galaxies using its characteristic spectral lines.
