What is the maximum number of electrons in an atom that can have the following quantum numbers?(a) n = 2; (b) n = 3 and ,= 1; (c) n = 3,,= 1,and m,= 0; (d) n = 3, ,= 1,m,= −1,and ms = −1/2.
解析 对中性原子来说,电子数等于电子序数.对离子来说,原子序数等于电子数加电荷数(阳离子)或电子数减电荷数(阴离子). 分析总结。 对离子来说原子序数等于电子数加电荷数阳离子或电子数减电荷数阴离子反馈 收藏
The meaning of ATOMIC NUMBER is an experimentally determined number characteristic of a chemical element that represents the number of protons in the nucleus which in a neutral atom equals the number of electrons outside the nucleus and that determines t
