And what we end up with for the energy then is 2.84 times 10 to the -19 joules.
我们算出的能量是,2，84乘以10的-19次方焦耳。
-
There's a sense of aliveness and energy, and in scientific terms everything is pure energy, so it's not that far-fetched.
有一种生机和能量，用科学的话来说，万物都是纯粹的能量，因此上面说法也不为过。
-
That means our energy is equal to 6.626 times 10 to the -34 joules times seconds.
这意味着能量等于,6，626乘以10的-34次方焦耳每秒。
-
And that makes sense, too, because the positive three pulling on minus one has a tighter binding energy than positive one pulling on minus one.
而这也是有意义的，因为+3和-1的相互吸引,产生了比+1和-1的吸引,更强的能量。
-
That's amazing, you can get atoms to smash atoms and create a chain reaction and create power-- that's a pretty amazing invention.
很惊人，你可以利用原子去做加速粒子,并产生连锁反应，然后创造能量-,那是个十分惊人的发明。
-
Mass and energy -- I'm an open system, right?
质量和能量--我是个开系，对吧？
-
Energy--pardon me?
什么能量,我没听清
-
So, if we took the case of nitrogen, if we add an electron to nitrogen and go to n minus, we find that the change in energy is 7 kilojoules per mole.
如果我们以氮为例，如果我们给氮增加个电子令它变成-1价的氮，我们会发现能量的变化是，7，千焦每摩尔。
-
So hopefully if some of you have your calculators with you, you can confirm the answer that I got, which is that the energy is 7.82 times 10 to the -19 joules.
所以如果你们带了计算器,希望你们也能确认一下，我们算出的答案，能量等于,7，82乘以10的-19次方焦耳。

And this is the energy level diagram for multi-electron atoms.
看一下能量级图表中,多电子原子的部分。
-
Any frequency can't have an energy, you have to -- you don't have a continuum of frequencies that are of a certain energy, it's actually punctuated into these packets that are called photons.
任何频率不能有个能量,你必须要-对某一个能量上,你不会有连续的频率,光子实际上分立的存在。
-
So, if we look at this graph where what we're charting is the internuclear distance, so the distance between these two hydrogen atoms, as a function of energy, -- what we are going to see is a curve that looks like this -- this is the general curve that you'll see for any covalent bond, and we'll explain where that comes from in a minute.
因此，如果我们来看一看这幅曲线图,这里我们画的横坐标是核间距，也就是这两个氢原子之间的距离，纵坐标是能量，我们看到的这是能量关于核间距的曲线-,这是一条普遍的曲线，在研究任何共价键时你都会遇到，我们马上就会解释一下它是怎么来的。
-
Anti-bonding is even higher in energy than non-bonding.
反键能量比非成键更高。
-
So, therefore, we can rewrite our equation in two ways. One is just talking about it in terms only of energy where our kinetic energy here is going to be equal to the total energy going in -- the energy initial minus this energy of the work function here.
所以我们可以把方程,写成两种形式，一个是,只考虑能量，动能等于总的,入射能量-初始能量减去,功函数的能量，我们如果想解决,比方说，我们想知道。
-
So z equals 7 -- this is the cut-off where, in fact, the sigma orbital is going to be higher in energy than the pi 2 p orbitals.
所以z等于7-这是分界点，实际上，sigma轨道能量,要比π2p轨道高。
-
And the reason is simply because the energy that Z we gain in terms of moving up in z, 5 so from going to z equals 4 to z equals 5, -- is actually outweighed by the energy it takes to go into this new shell, to go into this new sub shell.
原因很简单,就是因为我们通过提升，所得到的能量--从，Z，等于，4，到，Z，等于，事实上比填充到这个新的壳层,新的亚壳层，所消耗的能量更多。
