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”。 中文课本上介绍周期表分区的配图 [来自网络] 1.1原子与...

In the s-block and p-block of the periodic table, elements within the same period generally do not exhibit trends and similarities in properties (vertical trends down groups are more significant). However in the d-block, trends across periods become significant, and in the f-block elements sh...
