元素符号:Al中文名称:铝英文名称:Aluminum原子序数:13原子量:26.98外围电子排布:3s2 3p1核外电子排布:2,8,3常见化合价:+3密度:2.702溶点:660.37沸点:2519所属周期:3所属族数:IIIA原子半径:1.82离子半径:0.54(+3)共价半径:1.18同位素及放射性:Al-27发现人:Hans Christian Oersted发现时间:1825发现地点:丹麦名称由来:Latin: alumen, aluminis, (alum).元素描述:Soft, lightweight, silvery-white metal. Third most abundant element in the earth's crust.元素来源:Never occurs in free form. Obtained by electrolysis from bauxite (Al2O3).元素用途:Used for many purposes from airplanes to beverage cans. Too soft in its pure form so less than 1% of silicon or iron is added, which hardens and strengthens it.
