原子核外电子排布按照能量最低原理,按1s2s2p3s3p……进行电子排布,但由于能级交错现象的存在,电子排布次序变得复杂起来,使人们在进行核外电子排布的过程中变得很费力,而且极易弄错.本文介绍了一种既简单又实用的方法,使核外电子排布变得简单而轻松.大家知道,原子核外电子排布时分为K、L、 According to the principle of the lowest energy, the electron arrangement of the nuclei is performed electronically according to 1s2s2p3s3p ... However, due to the existence of the staggered energy levels, the order of the electron arrangement becomes complicated, which makes the process of changing the arrangement of electrons outside the nuclear It is laborious and easy to make mistakes.This paper presents a simple and practical method to make the arrangement of electrons outside the nuclear simple and easy.As we all know, the atomic arrangement of electrons is divided into K, L,
