The transition metals are important for many reasons, especially so because they form alloys that are extremely useful. Most of the metals have body-centered cubic, face-centered cubic, or hexagonal structures, but numerous transitions from one crystal structure to another are known (polymorphism)....

athe transition metals (for example, Cr, Cu, Ni, Zn,Mo, and Pb) was more complex, but most primary producers also had lower concentrations of these than the water. 过渡金属(例如,哥斯达黎加、Cu、Ni、锌、Mo和铅)比水是更加复杂,但多数更加主要的生产商也有这些的更低的集中。 [translate] ...

The transition elements are located in groups IB to VIIIBof the periodic table. In other words, the transition metals are elements: 21 (scandium) through 29 (copper) 39 (yttrium) through 47 (silver) 57 (lanthanum) through 79 (gold) ...
It may be seen that most of the elements, including all the transition and inner transition elements, are metals. 在周期表中,一条粗的阶梯状的线把元素划分为金属元素和非金属元素。处于线左边的元素(H 元素 除外)是金属元素,而处于线右边的元素是非金属元素。这种分法仅仅是为了方便。靠近线两边的元素...
Gold, the 79th element on thePeriodic Table of the Elements, is one of the more recognizable of the bunch. It is malleable and shiny, making it a good metalworking material. Chemically speaking, gold is atransition metal. Transition metals are unique, because they can bond with other element...
