I can then subsequently lose an electron from the lithium ion. Lithium ion loses an electron to become lithium 2plus.
然后我能在锂离子中，失去一个电子,锂离子失去一个电子,变为二价锂离子。
-
Electron affinity is actually the ability of an atom, or we could also talk about an ion to gain electrons.
电子亲和能其实就是一个原子，或者我们也可以讨论离子获取电子的能力。

There've been over 14 million hits to the site we've had from over 300,000 people and over 3 thousand email messages have been received.
收到了有超过30万人,三千多封电子邮件,这些电子邮件给了我们。

We actually have it on a spreadsheet as well: so here it is written out on a spreadsheet.
我们还制作了一张电子表格,所有信息都收录到了电子表格中
-
And we put up this hypothesis that our observation is that octet stability seems to be an attractive electron configuration.
我们把假设置于我们的观察之上,即8电子稳定体系,似乎是一种吸引人的电子图像。
-
What is the energy of the electron, the energy of this electron accelerating from rest and crashing into the anode here?
什么是电子的能量，电子能量由其他部分增大,撞击进入阳极？
-
What if we were to take this electron and send it over to here, in other words, engage in electron transfer.
如果我们得到这个电子,并把它放在这里，换句话说，我们做一个电子传送。
-
Right, we had one from each atom, so that means we need a total of two in our molecular orbital.
对吧，每个原子有一个电子，这意味着在分子轨道里我们一共需要两个电子。
-
Great. Yup, it's going to be an electron acceptor, it wants to accept electrons, it wants to accept electron density.
很好，没错，它将是一个电子的受主，它想要接收电子，接收电子密度。
-
Because that will take care of all of the electrons that are capable of reacting, none of the inner shell electrons.
因为那样我们可以考虑到,除内层电子以外，所有可以发生反应的电子。
-
OK, elements with low average valence electron energy, and here I'm saying below 11 electron volts, these are good electron donors.
平均价电子能都较低的元素，我是指那些低于11电子伏的，这些是很好的电子给体。
-
And you see where the most electronegative elements are, and fluorine is the most electronegative of the active elements.
你找一下电子力最大的元素在哪，氟是活泼元素中,电子力最大的。
-
The positive force of attraction of the electrons on the outside is greater and greater, and that pulls everything in.
所以对外层电子的吸引力,会越来越强，把电子们都向内吸引。
-
So this means that we have two of the electrons are lowered in energy, but two are raised in energy.
这意味着两个电子能量降低,两个电子能量升高。
-
In other words, for an electron donor to give up its electron, the electron donor needs to have an electron acceptor.
换句话说，如果一个电子给体要失去电子，它就必须找到一个电子受体。
-
And we can also write this in an even simpler form, which is what's called electron configuration, and this is just a shorthand notation for these electron wave functions.
而且我们也可以将它，写为一个更简单的形式，它叫做电子构型,这个仅仅是这些电子波函数的。
-
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。
-
Likewise, the element that is a good electron acceptor in an electron transfer reaction is going to be the element that is going to hog the electrons in a covalent bond.
同样的，这个元素在一个电子转移反应中,是个很好的受赠者它将成为在共价电子,中吸引电子的元素。
-
And we give different names, depending on what kind of electrons we're dealing with, so, for example, with h c l here, we can talk about having bonded versus lone pair electrons.
我们还起了不同的名字，给我们要处理的不同类型的电子，以氯化氢为例，我们来介绍一下成键电子与孤对电子。
-
The way that we can figure this out is using something called bond order, and bond order is equal to 1/2 times the number of bonding electrons, minus the number of anti-bonding electrons.
我们可以用叫做,键序的概念来弄明白它，键序等于1/2乘以成键电子,数目减去反键电子数目。
-
This should make sense, because if an atom has a very high electron affinity, that means it's really happy taking an electron from another atom, or taking a free electron -- that that's very favorable.
这应该是合理的，因为如果一个原子有很高的电子亲和能，这意味着,它非常乐意从另外一个原子那里夺取一个电子，或者得到一个自由电子--这是非常利于发生的。
-
I left out the noble gases here because they do something a little bit special, and actually, I'm going to give you one last clicker question today to see if you can tell me what you think noble gases do.
我并没有把稀有气体算在里面,因为它们的电子亲和能有点特别，实际上，我将会把这作为今天的,最后一个选择题，来请大家告诉我,你们觉得稀有气体电子亲和能应该是怎样的。
-
So, basically any time we have a really high positive number of electron affinity, it means that that atom or ion really wants to gain another electron, and it will be very stable and happy if it does so.
因此，基本上无论什么时候,只要我们有一个很大的正的电子亲和能，这就意味着这个原子,或离子非常希望得到一个电子，如果它得到了，会变得更稳定更开心。
-
Not only are we taking away an electron here, but we're also going to decrease shielding, so the electrons that are already in there are going to feel a higher z effective and will be pulling and the atom will be getting smaller.
这不只是因为我们拿走了一个电子，还因为我们这样做会减小屏蔽效应，这样留下的电子,将会感受到更大的有效核电量,也就会感受到更强的吸引力，使得原子变得更小。
-
So, we have beryllium in the first case here, it has four electrons, that's how we know it's beryllium, boron has five electrons.
那么我们将铍作为第一个例子，它有四个电子，这也是我们为什么能知道它是铍的原因，硼有五个电子。
-
But I can equate the amount of mechanical energy in the electron to the amount of electrical energy that was imparted through the electrodes.
但我们可以把电子中机械能量数量,和通过电极传送的,电子能量数量等同起来。
-
So we have 18 electrons, and the next thing that we need to figure out is how many bonding electrons we have.
那么我们有十八个电子，下一步要做的是判断,我们有多少个成键电子。
-
So you might ask in terms of when you're writing electron configurations, which way should you write it.
所以你们可能会问当你们,在写电子构型的时候，在写电子构型的时候。
-
OK, so now we've got, taken an electron from that sulfur, put it here, an electron from that sulfur, put it here.
现在我们得到的是，从硫那儿得到一个电子，放在这儿，一来自于硫的电子，放在这儿。
