So if we compare l increasing here, so a 3 s to a 3 p to a 3 d, what we find is that it's only in the s orbital that we have a significant probability of actually getting very close to the nucleus.
我们比较当l变大的时候,从3s到3p到3d,我们可以发现只有s轨道,有很大的概率,非常接近原子核。
So if we have a 3 d orbital, we're talking about n minus l minus 1, what is n equal to? What is l equal to?
如果我们有一个3d轨道,我们用n减去l减去1,n等于多少?l等于多少?
