錳 (Mg)的波尔原子模型
錳 (Mg)刘易斯点图
Description
Lightweight, malleable, silvery-white metal. Eighth most abundant element in the universe. Seventh most abundant element in the earth's crust.
Uses
Used in alloys to make airplanes, missiles and other uses for light metals. Has structural properties similar to aluminium. But since it is flammable at temperatures of burning gasoline, its uses are limited.
Sources
Usually obtained by electrolysis of melted magnesium chloride (MgCl2) found in sea water. Each cubic mile of seawater contains about 12 billion pounds of magnesium.
Pronounciation (English)
mag-NEE-zih-em
