这个非常简单的,一般规律每层电子层最多容纳2n^2电子,如K层容纳2个电子,L层容纳8个电子等等.依照规律很容易写出来,以钾元素为离子,为19号元素,共有19个电子,电子层排布为2,8,8,1.

一、核外电子排布所遵守的规则 多电子原子的核外电子排布是有规律的,首先是电子按层排布,而且每层最多容纳的电子数为2n~2个;其次,最外层电子数不得超过8个,而次外层的电子数则不能超过18个.这些规律是从实验和周期律

1s1 1s2 1s22s1 1s22s2 1s22s22p1 1s22s22p2 1s22s22p3 1s22s22p4 1s22s22p5 1s22s22p6 1s22s22p63s1 1s22s22p63s2 1s22s22p63s23p1 1s22s22p63s23p2 1s22s22p63s23p3 1s22s22p63s23p4 1s22s22p63s23p5 1s22s22p63s23p6

K 是2881Ca 是2882 这两个不遵寻元素核外电子排布规律其他的是最后一层最多8个!第n层是2乘以n的2次方倒数第二层最多是18个
