Well it is used in binding energy of the atom itself.

好吧，它用于原子本身结能。

The energy is in the binding energy.

该能量处于结能中。

This is known as binding energy and it's one of the fundamental principles of nuclear chemistry.

这被称为结能， 它是核基本原理之一。

This is a graph of the binding energies of various elements compared to their mass numbers.

这是各种元素结能与其质量数相比图表。

But elements with lower binding energies can react much more readily.

但是具有较低结能元素可以更容易地反应。

We also discussing binding energy and mass-energy equivalence, as well as the strong and weak nuclear forces.

我们还讨论了结能和质能等价，以及强力和弱力。

To find out how much binding energy that missing mass amounts to, you can use it as the 'm' in Einstein's formula.

丢失质量相当于多少结能， 您可以将其用作爱因斯坦公式中“m” 。

Well, that difference in mass is equal to an amount of energy, specifically the total binding energy of the nucleus.

那个质量差等于一定量能量，具体来说就是原子核总结能。

If you paid attention, you learned how Einstein's famous formula helps us calculate the binding energy of a nucleus from its mass defect.

如果您留心观察，就会了解到爱因斯坦著名公式如何帮助我们根据质量亏损计算原子核结能。

But while the total binding energy still increases for nuclei larger than iron, the binding energy per nucleon, in fact, decreases.

但是，虽然比铁更大原子核总结能仍在增加，每核子结能实际上是在减少。

That energy is what we mean when we talk about nuclear energy, the binding energy that's released when a nucleon is removed from its nucleus.

那种能量就是我们所说核能，当一个核子从其原子核中移除时释放结能。

That binding energy is how much energy you would have to add to the helium atom in order to break it apart its nucleus.

那种结能是你必须添加到氦原子上能量，以便将其原子核拆散。

And since binding energy accounts for the missing mass, you can calculate it using – you guessed it! – e equals m c squared.

由于结能解释了缺失质量，你可以用它来计算——猜猜看！——质能方程E=mc²。

The amount of energy required to break up a nucleus into its component particles gets larger as the atomic number increases, with iron having one of the highest binding energies per nucleon.

将原子核分解为其组成部分所需能量随着原子序数增加而增大，铁每核子结能之一是最高。

It's like, you know, the universe is expanding, but this room is not expanding because in this room, the binding energy of all the stuff is more important than the little bit of stretchiness of space.

就像你知道， 宇宙在膨胀，但这房间不会膨胀， 因为在这房间里，所有物体结能比空间那点微弱延展性更为重。
