<正> 长期以来,在国内外的一些《普通化学》或《无机化学》教科书中,对钠和钙两种金属活动性(也有叫”活泼性”的)次序的描述存在着两种矛盾的情况, 也常常是学生在学习本课程的过程中所遇到的基本概念搞不清的问题之一,故有必要提出讨论解决。如在以往的高中化学节〔1〕中描述金属的化学性质时“……一种金属元素的原子越容易失去电子,它的化学活动性也就越大。反之,它的活动性也就越小。事实上各种金属原子由于各自的结构上的不同,在失去电子时需要消耗的能量确是各不相同的。因此,金属的活动性确有着显著的区别。贝开托夫(于1865年发表的——作者注)所发现的金属活动性顺序,就跟金属失去电子的难易程度有关。金属活动性顺序表如表1:

For a long time, in some "general chemistry" or "Inorganic Chemistry" textbooks at home and abroad, there are two contradictory situations in the description of the order of the activity (also called "activeness") of sodium and calcium two metals, which is often one of the problems that students encounter in the process of learning this course, and it is necessary to discuss and solve.For example, when describing the chemical properties of metals in the previous high school Chemistry section (1), "...The more easily an atom of a metallic element loses electrons, the more chemically active it is.On the contrary, the less active it is.In fact, various metal atoms, due to their different structures, need to consume different amounts of energy when they lose electrons.Therefore, there is indeed a significant difference in the activity of metals.The order of activity of metals discovered by Bechtov (published in 1865 - author’s note) is related to the ease with which metals lose electrons.The order of metal activity is shown in Table 1:
