So then, I could say that the average valence electron energy for oxygen would then be, I've got two s electrons.
所以,我可以说,氧的平均价电子能,就是,以我得到的两个s轨道的电子来算。
Cameras and an inspection team spotted the bat clinging to the side of Discovery?s 15-story external tank as it was being fueled with propellant ? super-cold liquid hydrogen and liquid oxygen.
摄像机和一个检查小组捕捉到了这只蝙蝠的图像,它紧紧地贴在发现号15层的外置燃料箱上,当时正在进行灌注燃料(超低温的液氢和液氧)的程序。
So if we're talking about oxygen, 2s2 we would say that it's 1 s 2, then we have 2 s 2, 2p and then we have 2 p, and our total number of electrons 4 in the p orbitals are four.
所以如果我们在讨论氧,我们会说它是1s2然后我们有,然后,我们在p轨道的,电子总数是。

So, we can put our sulfur in the middle, and then it doesn't really matter how we draw the rest of it, where we put our c l's versus where we put our oxygen.
那么,我们可以把硫放在中间,然后把其它的原子画在哪里就不重要了,把两个氯原子与一个氧原子放在哪里都行。
We could also, I think, well, maybe this isn't written out in terms of that convention, which sometimes it's not, so let's also try writing it, such that we have the hydrogen and the oxygen atom there.
我们也可以,我想,好吧,还有可能它不是按照惯例写的,有时候会出现这样的情况,因此,让我们把氢原子和,氧原子成键的情况也写出来。
