periodic table of elements(元素周期表),简称periodic table(周期表)。 整个周期表根据元素价电子层排布方式被分为了五个大块的block(区): s-block,f-block,d-block,ds-block,p-block 这些区外,元素周期表还被人们划分为了更基本的“周期”与“族”。
table of elements, is an organized arrangement of the 118 known chemical elements. The chemical elements are arranged from left to right and top to bottom in order of increasing atomic number, or the number of protons in anatom's nucleus, which generally coincides with increasing atomic mass. ...
One of the early models of the periodic table arranged elements by atomic weight, which naturally grouped elements with similar properties together. 有种早期的元素周期表按原子量来排列元素,自然就将性质相似的元素放在一起了。 However, certain elements were outliers, and did not fit in their groups....
