Thekey differencebetween ionic and binary compounds is that离子化合物包含两个带电的成分,而二元化合物包含两个不同的化学元素。
Ionic compounds are binary compounds that come under two different categories. Ionic compounds come under covalent compounds when we analyse the chemical compounds according to the type of chemical bonds present in the molecule. On the other hand, binary compounds come under the classification of compounds depending on the chemical elements present in the molecule.

What are Ionic Compounds?
Ionic compounds are chemical compounds containingcations and anionsheld together by ionic bonds. An ionic bond is an electrostatic attraction force. This attraction occurs between opposite charged ions (cations or positively charged ions and anions or negatively charged ions). These compounds form as a result of atoms tending to complete their electron configuration in order to obtainnoble gas电子配置,这是这些原子可以存在的最稳定的方式。此外,离子化合物通常作为晶体存在,因为具有相对带的离子物种倾向于聚集。
When considering the nomenclature of ionic compounds, we need to give the name of the cation first, followed by the name of the anion. There are different ways of naming these compounds. For instance, we can name the cation by indicating the oxidation state using Roman numbers, i.e. iron(II) or iron(III). Or else, we can name them using suffixes, i.e. ferrous or ferric. When naming the anion, if it is monoatomic, we can use the suffix –ide, .g.F–is fluoride and O2-is oxide. Moreover, we can name oxygen-containing polyatomic anions using –ite and –ate suffixes, e.g. NO2–是亚硝酸盐。
What are Binary Compounds?
Binary compounds are the chemical compounds containing two different chemical elements. Moreover, the type of chemical bond between the atoms of these two chemical elements can becovalent bonds, ionic bondsor even coordination bonds.
Furthermore, no matter what the ratio between the atoms in chemical formula is, if there are only two types of atoms, then it is a binary compound.
离子化合物和二元化合物有什么区别?
The key difference between ionic and binary compounds is that ionic compounds contain two charged components whereas binary compounds contain two different chemical elements. Moreover, ionic compounds essentially have ionic bonds, but in binary compounds, ionic bonds may or may not present.
摘要 - 离子与二进制化合物
There are different classifications for chemical compounds. Ionic compounds and covalent compounds are classified depending on the chemical bonds between atoms. The key difference between ionic and binary compounds is that ionic compounds contain two charged components whereas binary compounds contain two different chemical elements.
