按照门氏的元素周期律,元素可分为金属与非金属两类。这两类元素具有不同的特征,而这些特征一般亦表现在相应单质的结构中。因此,我们有必要从单质结构的比较研究中来进一步揭露与说明这两类元素在其相应单质中表现的各项特征。现在,极大多数单质的晶体结构已被测定,从而各种原子在单质中的结合方式亦属已知,因此上述比较研究亦已著有成效。现将各种单质的晶体结构数据按元素周期系列举在表1中(见附表)。
In accordance with the Men’s Periodicity of the elements, the elements can be divided into two types of metal and non-metallic. These two types of elements have different characteristics, and these characteristics are also generally expressed in the structure of the corresponding elemental. Therefore, it is necessary for us to further reveal and illustrate the characteristics of these two kinds of elements in their corresponding simple elements from the comparative study of simple structure. Now that the crystal structure of most simple elements has been determined, the way in which various atoms are bound in a single element is also known and the above comparative studies have also been successful. Now the crystal structure of a variety of elemental data according to the periodic list of elements in Table 1 (see table).
