确定氢在周期系中的位置问题,进行若干补充讨论是非常必要的。关于氢在周期系中位置问题,一直存在着不同的意见。在目前几本通用的普通及无机化学教科书中,对氢在周期系中的位置的问题,有下列几种意见:一种是把氢列入碱金属——第一族,另一种是把氢列入第七族。第三种情形,是不把氢列入周期系的各个族。下面就各种情况加以论述:按照氢原子的电子结构,它像碱金属元素一样,在最外层只有一个电子。因而能失去一个电子(价电
Determine the location of hydrogen in the periodic system problems, a number of additional discussions is necessary. There have always been differences of opinion regarding the location of hydrogen in the periodic system. In the current general textbooks of common and inorganic chemistry, there are several opinions on the position of hydrogen in the periodic system. One is the inclusion of hydrogen in the alkali metal - the first group, the other is the Hydrogen included in the seventh group. The third scenario is not to include hydrogen in the various clans of the periodic system. The following is a description of a variety of situations: According to the electronic structure of hydrogen atoms, it is the same as the alkali metal elements, the outermost only one electron. Thus can lose an electron (price electricity
