主族元素的最后一个电子是排在最外层;副族元素的最后一个电子是排在次外层.

看看这个吧,电子的,非常详细.

氢、氦没有电子排布简式3锂Li[He]2s14铍Be[He]2s25硼B[He]2s22p16碳C[He]2s22p27氮N[He]2s22p38氧O[He]2s22p49氟F[He]2s22p510
就是写1s22s22p6这种东西.原子排布图看不出来电子轨道的改变(就不知道是基态还是激发态).
钯为第5周期,应该有五层电子,但钯为副族元素电子构型:1s22s2p63s2p6d104s2p6d10所以为281818

3d54s2中3代表第三电子层,d代表电子亚层编码,5指3d亚层有5个电子;4表示第四电子层,s是电子亚层代码,2表示4s亚层有2个电子.一、原子核外电子排布的原理处于稳定状态的原子,核外电子将尽可能
2,8,18,32,32,16,2外层电子构型是6d87s2

点开该元素就可以了查看第7行

自己看元素周期表啊,电脑很难打出那种形式的
