元素周期表是1869年门捷列夫首先提出元素的周期律并列表来表示元素性质的周期变化,及元素间的关系。目前中学及大学教科书都印有周期表,并在有关章节加以解释。后来有很多化学家对元素周期表进行研究并提出自己的看法。现在应用最广的是改进的维尔纳式元素周期表。本文介绍一种新的设想称三维元素周期 Periodic Table is the Mendeleev first proposed in 1869 periodic list of elements and periodic changes in the nature of the elements, and the relationship between the elements. At present, secondary school and university textbooks are printed on the periodic table, and in the relevant sections to be explained. Later, many chemists studied the periodic table and put forward their own views. The most widely used is now the modified Werner-type periodic table. This article describes a new concept called 3D elemental cycles
