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

这被称为结能， 它核化学的基本理之一。

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效，以及强核力和弱核力。

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

这各种元素的结能与其质量数相比的图表。

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

但具有较结能的元素可以更容易地反应。

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

好吧，质量差等于能量，特别核的总结能。

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

但，虽然对于比铁大的核，总结能仍然增加，但实际上每个核的结能却降了。

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

要找出丢失的质量相当于多少结能， 您可以将其用作爱因斯坦公式中的“m” 。

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.

当我们谈论核能时，这种能量就我们所说的能量，即当核从其核中移除时释放的结能。

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

该结能您必须向氦添加多少能量才能将其分解成核。

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的质量，您可以使用 - 您猜对了！ – e 等于 m c 的平方。

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的公式如何帮助我们根据质量亏损计算核的结能。

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.

随着序数的增加，将核分解成其组成粒所需的能量会变大，铁每个核结能最高的物质之一。
