A table with common ionic charges can also help determine oxidation states and chemical reactions. For example, knowing that iron can have a +2 or +3 charge can help predict the formation of compounds like FeO (iron(II) oxide) or Fe2O3(iron(III) oxide). Based on the common charges,...

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...
Halogens are nonmetal elements located on the right side of the periodic table in Group 7. Halogens include the elements of florine, chlorine, bromine, iodine and astatine. Halogens have a negative 1 charge and are considered very reactive. ...

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...
1. The Elements and The Periodic Table(元素和周期表) The number of protons in the nucleus of an atom is referred to as the atomic number, or proton number, Z. The numbers of electrons in an electrically neutral atom is also equal to the atomic number, Z. The total mass of an atom ...
