So we need to go to this second case where we're instead going to think about electronegativity, and we want to think about which atom is the most electronegative.
因此我们需要转到这个第二种情况,来考虑一下电负性,我们需要想想哪个原子的电负性是最高的。
We haven't had... there are three Princetonians on the Supreme Court right now.
我们还没有……有三位普林斯顿的毕业生在最高法院任职。
So a plus two ion means that we're removing two electrons from the atom and the electrons that we're going to remove are always going to be the highest energy electrons.
一个2价正离子,我们要移除的两个电子,我们要移除的两个电子,将会是,最高能量的电子。
All right, now, let's take the other part of the poll, which is the highest experience or pleasure.
好,现在我们再投个票,哪个是最高级的体验或者快乐。
We'll assume that if there's a tie that we flip a fair coin or a Supreme Court judge, whatever you want to take, whichever.
我们将假设如果有人票数一致,我们就掷硬币或由最高法院裁决,不论你们想用那种方法
So, that really won't do the trick in giving us the best quality pleasures of the kinds that humans most crave-- the pleasures of friendship and discussion and sexual intimacy.
那无法给与我们,人类最渴望最高质量的快乐-,友谊,讨论,性事带来的快乐。
when the project was presented not only the sponsors but also the business heads that would be the top two layers of the organization listen to the project, evaluate them, and then feedback whether or not they would be taking them forward and putting them into practice.
在将项目呈现给,该组织的最高层,即主办方和业务主管时,我们让他们,听项目报告并进行评价,然后针对是否会,录用他们并让他们,参与实践给出反馈。
There's no sense that we're making God up in this kind of discourse.
我们没有理由将上帝看作最高级的存在。
We're trying to see how high that is.
我们来计算,最高点在哪儿
We didn't even have income tax until 1913 when the Supreme Court allowed it, so it was zero, then it went up to 90%-- or actually it was 94% at the peak--and it came down to 15%.
直到1913年最高法院允许征收的时候,我们才开始征收所得税,开始税率是零,而后飙升到90%,然后它最高达到94%再降到15%
And when we bought, it was at the height of the housing bubble,
我们买房子的时候,正是房地产泡沫的最高峰,
We were on the roof of America and all we could do was yell I guess across the night, eastward over the plains where somewhere an old man with white hair was probably walking towards us with the word and would arrive any minute and make us silent.
我们在美国的最高处大声叫喊,我想整个夜晚,在东部平原,随时可能有一个白发老人,向我们走来,让我们安静。
We'd convene some of the most senior members.
我们会召集最高职位的官员。
You can see that when you get out to the highest groups here, the highest weights, the relative risk is up at two and a half or three, so that would be a 200% increase in risk for cardiovascular death or two to three times the risk of death.
当我们看图上相对风险最高的这组,也就是体重最大的这组,这组的相对风险大约是2.5倍到3倍,即心血管疾病致死的风险增加了200%,或者说增加了2到3倍
At first it might be counter-intuitive because we know the probability density at the nucleus is the greatest.
起初我们觉得这和直观感觉很不相符,因为我们知道在原子核,出的概率密度是最高的。
py And finally, we can look at the 2 p y, so the highest probability is going to be along the y-axis.
最后我们来看一下,概率密度最高的是沿着y轴。
And at the end of class we'll announce which recitation that is, we'll also make sure to give you a little bit of a prize if you are, in fact, in that recitation.
而且在这节课的最后,我们将会宣布哪个讨论小组答题正确率最高,并给这个小组的每位同学,发个小奖品。
OK, good. This might be our all-time high, 89% got this right. This is great.
好的,很好这可能是我们上课以来正确率最高的一次,89%,的同学都做对了,这太棒了。
So that's why we see the 2 p here, 1206 the 2 s is 12 06, and it makes sense that what we see as the greatest ionization energy, which is also the smallest kinetic energy is that 1 s orbital.
这就是为什么我们看到,2,p在这里,2,s对应,那么我们看到对应最高的电离能,同时也对应最低的动能的,应该就是,1,s,轨道。
We know that it has to be equal to less than 2, because even if we had absolutely no shielding at 2 all, the highest z effective we could have is 2, so it makes perfect sense that we have a z effective that falls somewhere in the middle of those two.
我们知道它必须小于,因为即使完全没有一点屏蔽,最高的有效的z是,所以我们得到的有效电荷量处于,两者之间就非常讲得通了,让我们来看看另一个例子。
So in the case of 12 32, that is our highest kinetic energy, it's the smallest amount of energy it takes to pop an electron out of that orbital.
因此,1232是我们能够得到的,最高的动能,它是从这个轨道中,打出一个电子需要消耗的最低能量。
We don't know the time and we don't know how high it's rising so you can ask, "How am I supposed to deal with this problem?"
我们既不知道时间,又不知道最高点的高度,那你就会问了,这道题该怎么做呢
Now, we are done because now we can ask how high does it go, and you go back to your y of 1 is 15+10-5, which is what?
现在问题解决了,因为我们可以算出,最高点的高度,你回到这个式子,求出y=15+10-5,是多少
