23、数相同而中子数不同的同一元素的不同原子互称为同位素。( 对于原子来说 ) 二、元素周期表1. 编排原则：按原子序数递增的顺序从左到右排列将电子层数相同的各元素从左到右排成一横行。 （周期序数原子的电子层数）把最外层电子数相同的元素按电子层数递增的顺序从上到下排成一纵行。主族序数原子最外层电子数2. 结构特点：核外电子层数元素种类第一周期 1 2种元素短周期第二周期 2 8种元素周期第三周期 3 8种元素元（7 个横行）第四周期 4 18种元素素（7 个周期）第五周期 5 18种元素周长周期第六周期 6 32种元素期第七周期 7 未填满（已有26 种元素）表主族： A A共 7 个主族族副族：
