元素符号:Mg
中文名称:镁
英文名称:Magnesium
原子序数:12
原子量:24.31
外围电子排布:3s2
核外电子排布:2,8,2
常见化合价:+2
密度:1.738
溶点:648.8
沸点:1090
所属周期:3
所属族数:IIA
原子半径:1.72
离子半径:0.72(+2)
共价半径:1.36
同位素及放射性:*Mg-24 Mg-25 Mg-26
发现人:Sir Humphrey Davy
发现时间:1808
发现地点:英格兰
名称由来:From Magnesia ancient city in district of Thessaly, Greece.
元素描述:Lightweight, malleable, silvery-white metal. Eighth most abundant element in the universe. Seventh most abundant element in the earth's crust.
元素来源: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.
元素用途: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.
