More so than any of the other major groups of elements in the periodic table, the transition metals have shaped human history and have been the workhorses of industry. The discovery of metallic copper ended the Stone Age and ushered...
周期表上,一个元素的基本信息一般都会被标注在元素的符号(symbol / chemical symbol)周围。 化学里的元素(element)基本可以分成 metal(金属) 与 nonmetal (非金属) 两类,金属元素又有一系列特别的 transition metals(过渡金属)。周期表上金属与非金属交界处又有着一系列具有特殊性质的元素,被称为 metalloid(准金属...
Transition Metals: Central block elements, multiple oxidation states, good conductors. Lanthanide Series: Rare earth metals from lanthanum to lutetium, used in high-tech. Actinide Series: Includes elements like uranium and plutonium, mostly ...
