一道有关电子的化学题
Two electrons with the same n,l,and ml values
(A)must be in different atoms
(B)are in different orbitals of the same subshell
(C)are in the same orbital of the same subshell with opposite spins
(D)are indistinguishable from each other
(E)None of the above
希望给出答案的同时,l,ml,ms的概念~

关于电子方面的,那n就是主量子数,n相同的电子成为同层电子,用符号K,L,M,N……表示.l即为角量子数,只能是小于0的正整数,相应的电子成为s(0),p(1),d(2),f(3)……电子.m为磁量子数,由l来决定,取0~±l
ms为自旋量子数,只是表示电子的两种不同状态,只能为1/2,-1/2.
所以,若两个电子的你n,l,m值都相同,那么自旋量子数必然不同!(在同一亚层,但自旋方向相反.)
