一、表中用弧线表示周期,实弧线连接原子中电子充填s分层和p分层的元素,长虚弧线连接d分层元素,点虚弧浅连接f分层元素。并且用箭号表示元素原子中电子开始填充新主层(开始新周期),或开始充填另一分层二、表中用罗马字母(Ⅰ.Ⅱ)表示族,实线连接的元素在它们处于任一相同氧化态时,外层电子层结构相同,长虚线连接的元素,除去与所在编号相当的氧化态外(最高氧化态),当氧化态相同时,具有相同最外电子层。点虚线连接的元素只处在与所在族的编号相当氧化态时,才具有最外相同电子层。
1. In the table, the cycle is represented by an arc, the real arc connects electrons in the atom, the s layered and p layered elements, the long virtual arc connects the d layer elements, and the point virtual arc connects the f layer elements. And use arrows to indicate that the electrons in the element atom begin to fill the new main layer (begin the new cycle), or begin to fill another layer 2. In the table, the family is represented by the Roman letter (I.II), and the solid line connected elements are in their In any of the same oxidation states, the outer electron layer has the same structure, and the elements connected by the long dashed lines, except for oxidation states corresponding to the same number (highest oxidation state), have the same outermost electron layer when the oxidation state is the same. Elements connected by dashed lines only have the same outermost electronic layer when they are in the same oxidation state as the family they are in.
