In the second case, I found in the next smallest element and moved here, taking what was there and moving it on, in this case I would swap the 4 and the 8, and in next case I wouldn't have to do anything.
在第二次遍历中,我找到了,第二小的元素,把它移到这里,把这里原来的元素移到哪里,在这一次遍历中,我会把8和4交换,然后一次遍历,不会做任何事情。
Advance this pointer-- this finger, to the next element of the list which is 4, make the comparison.
前移这个指示器--也就是这根手指,让它指向列表中的,下一个元素4,再做比较。
s1 So for the fourth period, now we're into the 4 s 1 3d for potassium here. And what we notice when we get to the third element in 4s2 and the fourth period is 3d that we go 4 s 2 and then we're back to the 3 d's.
对于第四周期到现在我们来到钾的1,然后我们返回到,我们注意到当我们看到第三个元素,第四周期我们来到,然后我们返回到。
So we want to look at any element that has a 3 p orbital filled, but that does not then go on and have a 4 s, because if it had the 4 s filled then we would actually see six lines in the spectrum.
所以,我们要找一找有哪些元素的,3,p,轨道被占据,但没有,4,s,轨道被占据,因为如果,4,s,轨道也被占据了,那我们会在光谱中看到第六条谱线。
