现行初中全一册化学课本在讲到离子化合物时对离子下了如下定义:“这种带电的原子叫做离子(注①:带电原子团也叫离子,如硫酸根离子SO_4~(2-)、氢氧根离子OH~-)。(P.83)高中教材在讲到离子结构特征时,再一次定义:”离子是带电荷的原子团“。(见乙种本上册P.111、甲种本第二册、P.3)稍一推敲就不难发现,教材在给离子这一化学概念(术语)下定义时,将它与原子的概念混淆了。事实上,原子和离子是两个完全不同的 The current junior middle school chemistry textbook teaches ionization when it comes to ionic compounds: ”The charged atom is called an ion (Note 1: The charged radical is also called an ion, such as sulfate ion SO_4~(2-), Hydroxy ion OH~-.(P.83) When the high school textbooks talk about the ionic structure characteristics, it is defined once again: “Ions are charged atomic groups” (see class B on page P.111, A). In this second volume, P.3), it is not difficult to find that when the teaching material is defined under the chemical concept of ion (term), it confuses it with the concept of atoms. In fact, atoms and ions are two. Totally different
