Why is magnesium not found naturally?
Magnesium makes up 2 percent of the Earth’s crust, but you won’t see this silvery, light metal in nature. This versatile element occurs naturally only in combination with other elements, such as carbon, calcium and oxygen, as in the common mineral dolomite.
Where is magnesium typically found?
On Earth, magnesium is found both in the crust and in the mantle; it’s also the third-most abundant mineral dissolved in seawater, with a 0.13 percent concentration. After Davy isolated magnesium in 1808, several scientists worked to purify the metal using various methods, according to the USGS.
What foods are highest in magnesium?
