金属是一种具有光泽(对可见光强烈反射)、富有延展性、容易导电、传热等性质的物质。金属的上述特质都跟金属晶体内含有自由电子有关。由于金属的电子倾向脱离,因此具有良好的导电性,且金属元素在化合物中通常带正价电,但当温度越高时,因为受到了原子核的热震荡阻碍,电阻将会变大。金属分子之间的链接是金属键,因此随意更换位置都可再重新创建链接,这也是金属伸展性良好的原因之一。

在自然界中,绝大多数金属以化合态存在,少数金属例如金、银、铂、铋可以游离态存在。金属矿物多数是氧化物及硫化物。其他存在形式有氯化物、硫酸盐、碳酸盐及硅酸盐。

Metal 金属

hcp and fcc close-packing of spheres
Gallium crystals
Filling of the electronic states in various types of materials at equilibrium. Here, height is energy while width is the density of available states for a certain energy in the material listed. The shade follows the Fermi–Dirac distribution (black=all states filled, white=no state filled). In metals and semimetals the Fermi level EF lies inside at least one band.
In insulators and semiconductors the Fermi level is inside a band gap; however, in semiconductors the bands are near enough to the Fermi level to be thermally populated with electrons or holes.

Hot metal work from a blacksmith.

A metal (from Greek μέταλλον métallon, "mine, quarry, metal") is a material (an element, compound, or alloy) that is typically hard, opaque, shiny, and has good electrical and thermal conductivity. Metals are generally malleable — that is, they can be hammered or pressed permanently out of shape without breaking or cracking — as well as fusible (able to be fused or melted) and ductile (able to be drawn out into a thin wire). About 91 of the 118 elements in the periodic table are metals, the others are nonmetals or metalloids. Some elements appear in both metallic and non-metallic forms.
